摘 要:
基于1990~1999年逐周的(18×18)km分辨率的海表温度(SST)资料,将其与历史资料(1959~1982)对比,发现近10年渤海SST较历史SST要高,但整体结构特征变化不大。进一
步采用EOF方法对渤海SST异常(SSTa)进行分析,得到3个主要的模态。第一模态对总方差的贡献为82.4%,表现为整个海区SSTa同步升温或降温的特征,结合渤海沿岸2个测站的气温资料的分析,认为渤海SSTa第一模态的变化与渤海气温异常变化相互依存,另外,北黄海SSTa的变化可能是造成渤海SSTa第一模态在海峡口附近变化幅度大的主要因素。第二模态对总方差的贡献为9.4%,在空间上其对整个海区SSTa起东升温(东降温)则西降温(东升温)作用,可
能是ENSO现象影响渤海海温变化最直接的表现。第三模态对总方差的贡献为5.0%,在空间上其对SSTa起北升温(北降温)则南降温(南升温)的作用,认为其可能与山东陆域气温和黄海流域气温变化有关。

Abstract: Based on the Bohai Sea SST data in the period 1990~1999 and the
historical data in the period 1959~1982, the characteristics of the interannual
variability of the sea surface temperature anomaly (SSTa) are
analyzed. It is found from the two datasets that the mean SST of the Bohai Sea
in the period 1990~1999 is higher than it was in the period 1959~1982, but they
had similar spatial structure. EOFs are used to analyze the interannual
variability of SSTa in the Bohai Sea. The first EOF component, which accounts
for 82.4% of the total variance, indicate that the SST increased or decreased
synchronously in the whole Bohai Sea. The analysis of two coastal station data
suggests that this may have been caused by the local airsea interaction. And
the north Huanghai Sea SSTa may have resulted in the “tongue" shaped pattern of
the first EOF mode in the area near the Bohai strait. The second EOF component
with an east west structure, accounting for 9.4% of the total variance, was
possibly the direct result of the impact of ENSO events. The third EOF
component, which accounts for 5.0% of the total variance, demonstrates the
northsouth structure of SSTa and may beenrelated to land temperature
variability.

摘 要:
利用实况观测和北京T213数值预报资料,对2003年9月3~4日山东雨季最后一场大暴雨过程进行了诊断分析。结果表明,本次大暴雨是由在广东登陆的热带气旋倒槽北伸与西风带弱冷空气相结合的产物。伴随登陆热带气旋生成的低空东南急
流为暴雨输送了丰富的热量和水汽,低层增暖增湿促使层结不稳定加剧,而西风带弱冷空气的侵入对暖湿空气具有抬升作用,可触发对流发展和不稳定能量释放,导致大暴雨产生。鲁中山区西南侧有利地形促使了低层气旋环流的形成,对暴雨具有明显的增幅作用,是该地区出现暴雨中心的重要原因。

Abstract: A diagnostic analysis is performed of the last severe storm in the
summer of 2003 that occurred during 3~4 September in Shandong Province using
observations and Beijing T213 model output data. The results show that the heavy
storm was caused by the interaction between a tropical cyclone trough that
landed in Guangdong Province and a weak cool front in the westerlies. The
southeast low air jet accompanying the tropical cyclone transported plenty of
heat and moisture for the storm, the lowlevel heating and wetting weakeed the
stability of the air, and the weak cool air intruded from the lowlevel and
stimulated the convection, thus leading to the heavy storm. The topographic
influences in the southwest of central Shandong are in favor of the formation of
the lowlevel cell, which amplified the rainfall intensity and resulted in the
precipitation center
there.

Abstract: A typical extreme hightemperature weather event warmer than 40℃ was
observed in a large area of north China at 06UTC 15 July 2002. This event
significantly influenced people's life, and attracted the news media's concern.
In this paper, almost all available observational data are employed to document
its
evolutionary process and to investigate its mechanism. The synoptic situations
from lowerlevel to upperlevel prior to and during the hightemperature event
are analyzed. Also, the spatialtemporal distributions of various variables are
described. Through thermodynamics equation, it is indicated that this extreme
hightemperature weather event was mainly caused by the joint effects of the
advection of potential temperature, the vertical transportation of potential
temperature and non adiabatic heating.

摘 要:
为深入了解气候变化规律及探讨气候变化原因,根据1900~2002年青岛月平均气温资料,分析了103年以来青岛的气温变化特征。分析结果表明:百年来,青岛平均气温呈明显上升趋势,各季节也是增温趋势,冬季增温最大。最高气温和最低气温也都呈明显上升趋势,其中最低气温的变化幅度大于最高气温的变化幅度。对比2次暖锋期的增温特点发现,20世纪40年代的增温主要是春秋季节的增温造成的,而20世纪90年代以后的增温期冬季成为主导因素,同时都是最低气温贡献大,即增温都是在夜间。日较差则呈下降趋势。青岛的气温在1988年发生了突变。另外,青岛气温还有准20年周期振荡的特征。

Abstract: Based on the monthly mean temperatures in Qingdao from 1900 to
2002,the characteristics of temperature change over the past 103 years are
analyzed. The results show clearly that the mean temperature is increasing, so
is the mean temperature in each season, especially in winter. The diurnal
maximum and mini
mum temperatures also increase and the increase of the minimum temperature is greater
than that of the maximum temperature. Contrasting and comparing the
characteristics of the two warming periods, we find that the warming in the
1940s mainly occurred in spring and autumn, but the warming from the 1990s up
to present mainly accurres in winter. For both periods, the main contribution to
the warming came from the increase of minimum temperatures, i.e., the
temperature increase took place at night. The DTR showed a trend towards
decreasing. ln addition, it is found that the abrupt change in temperature in
Qingdao occurred in 1988. Besides, the Qingdao temperature is characteristic of
oscillations with quasi20 year periods.

PAN Luqing, WU Zhongwang, ZHANG Hongxia
(The Key Laboratory of Mariculture, Ministry of Education, Ocean University of
China, Qingdao 266003, China)
Abstract: The effects of three kinds of metal ions (Cu2+,Zn2+,Cd2+) on different
tissues of Litopenaeus vannamei were studied. The results showed that:
Transaminases (GOT,GPT) activities of different experimental groups in three
tissues changed significantly with time (P<0.05).And the activities of GOP and
GPT decreased significantly in the gills and hepatopancreas, but increased
significantly in the blood while no significant changes were found in the
control groups (P>0.05). In addition, the effects of the three metal ions on the
transaminases activities positively correlated with the concentration of the
ions and the changing trends were identical on the whole. The inhibition rates
of Cu2+ on the activities of GPT in the gills and hepatopancreas were greater
than those of GOT. The inhibition rates of Zn2+ on the activities of GPT in the
hepatopancreas were lower than those of GOT. However, the inhibition rates on
activities of GPT in the gills were greater than those of GOT in the
lowdose(1~2mg/L) groups but lower than those of GOT in the highdose(5~10mg/L)groups.
The inhibition rates of Cd2+ on the activities of GPT in the hepatopancreas were
lower than those of GOT and were greater than those of GOT in the gills.
However, the activation rates of the three metal ions on the activities of GPT
in the blood were lower than those of GOT.

Abstract: FZ hapten was coupled to BSA and HSA by an improved Diazotization
procedure. The antibodies were obtained successfully by immunizing New Zealand
rabbits with FZBSA. FZHSA was artificial coating antigen. The indirect
competitive ELISA for FZ was developed. No crossreactivity was seen between
antibody and five other anitbiotics including chloramphenicol, sulfamethazine,
erythromycin, enrof loxacin and trimethoprim. The antibody showed that the
crossreactivity for furacilinum was no more than fortyfive percent. The
results of the experiment demonstrated that the optimal concentrations of the
coating antigen, polyclonal antibody against FZ and sheep antirabbit IgG were
1.25μg/mL, 1∶3 200 and 1∶1 000, respectively. A standard curve was obtained,the
regression equation was y=95.381-20.203x (R2=0.991 3). The average recovery rate
of shirmp m

Abstract: The genetic similarities of silver crucian carp (Carasssius auratus
gibelio) (CAG), allogynogenetic silver crucian carp (ASCC), parahybrids of
allogynogenetic silver crucian carp and red common carp (PHAR) and red common
carp (Cyprinus carpio) (CC) populations were determined by RAPD analysis. The
polymorphic band numbers of CAG, ASCC and PHAR are similar to each other, but
lower than that of CC significantly. Some bands are specific for or unique to
PHAR. The similarities between CAG and ASCC are higher than those between CAG
and PHAR, while the similarity between CC and ASCC is lower than that between CC
and PHAR. These findings imply that a diploid population is more diverse than
triploid populations; genetic recombination has occurred in the PHAR genome; and
PHAR becomes similar to CC gradually with the increase of CC sperm stimulation
times. When CC s
perm stimulates the development of triploid ova, it may integrate some of its
genetic materials into ASCC and PHAR genomes, providing a genetic basis for
their economic trait superiorities.

Sciences, Guangzhou 510300, China)
Abstract: Fish resources was surveyed in seven coral reef water areas in the Xisha
Islands including Lanhua reef, Dong Island, Huaguang reef, Yongxing Island,
Jinyin Island, Yuzhu reef and Bei reef by longlining and bottom gillnetting in
May 2003. The total fishing efforts of the survey included longlining 3 740
hooks
and bottom gillnetting 14 480m. Single fishing effort was longlining 80120
hooks and bottom gillnetting 120800m separately. 3 700 ind in 177 species were
caught, and the total catch quantity was 2 767.00kg. 77 ind (1 711.55kg) in 33
species were caught by longlining and 153 species 3 623 ind (1 055.45kg) were
caught by bottom gillnetting. The mean catch rate was 2.06 ind·(100hooks)-1 by
longlining and 250.21 ind·(1km)-1 by bottom gillnetting per reef. The CPUEs were
45.76kg·(100hooks)-1 by longlining and 72.89kg ·(1km)-1 by bottom gillnetting
per reef. The major commercial species included sharks, morays, groupers,
snappers, pigface breams, parrotind, mullets, etc. Fish resources are extremely
abundant in the water area of Bei reef, Jinyin Island and Yuzhu reef and the
exploitation potential is high. Although the fish resources and exploitation
potential are r
elatively lower in the water areas of Lanhua reef, Dong Island, Huaguang reef
and Yongxin Island, they are of exploitation value to a certain extent.

摘 要:
对1950~2000年的51年黄河经利津水文站入海的逐日水沙实测资料进行统计分析,展示了黄河入海水沙的极端情况,如洪峰和沙峰等逐渐变少到消失的过程及逐日入海水沙量的变化规律,并对其影响因素进行了初步分析。结果显示:在黄河年均入海水沙锐减的背景下,20世纪90年代日均流量<500m3/s的天数增加到了是20世纪50年代的3倍多;>2
000m3/s的洪季流量由初期频发至1997年消失;>4 000m3/s的洪峰流量自1989年以后消失;>6
000m3/s的洪峰流量从1986年就不再发生。>500t/s
的日均输沙率(43.2×106t/d的沙峰)都出现在1989年以前;>700t/s的日均输沙率(60.5×106t/d的沙峰)出现在1977年以前;含沙量>80kg/m3的历时和可能产生异重流的含沙量天数都逐步减少。进入20世纪90年代以来基本不存在大洪灾及由沙峰造成的河口河道快速堆积而使河流改道现象,引起这些变化的因素除降雨外主要为流域耗水量不断增加及大中型水库的建成运用等,黄河入海水沙的这种锐减及水沙峰的极端情况都会对河口演变和河口区的生态环境产生重要的影响。

The Daily Variations of the Water Discharge and Sediment Discharge Into the Sea
from the Yellow River from 1950 to 2000 and the Relevant Influential Factors That
Generate These Changes

Abstract: This paper analyzes the daily variations of the water discharge and
sediment discharge through Lijin Hydrologic Station from 1950 to 2000, and
indicates the extreme circumstances including the processes in whic
h the flood peak and sediment peak decreased and disappeared in the past 51
years. This paper also demonstrates the changes and laws of the water and
sediment discharge flowing into the sea. The result displays that, with the
sharp decrease of the yearly average volumes of water and sediment discharges,
the number of days with daily discharge under 500m3/s was over three times
greater in the 1990s than in the 1950s, the flood discharge surpassing 2 000m3/s
frequently occurred at the earlier stages but disappeared in 1997, the flood
peak discharges over 4 000m3/s have disappeared since 1989 and those exceeding 6
000m3/s have disappeared since 1986. At the same time, the daily average
sediment discharges surpassing 500t/s occurred before 1989 and those exceeding
700t/s disappeared after 1977. The number of days when the daily average
sediment content was over 80kg/m3 and probably generated Hyperpgenal plumes
gradually decreased in the past 51 years. The water consumpti
on increase and the large and mediumsized reservoirs built in the river mainstream
have negative effects on the water and sediment discharge. Both the sharp
decrease of the water and sediment discharges and the extreme circumstances such
as flood peak and sediment peak have a great negative effect on the estuarine
evolvement and estuarine ecological environment.

摘 要:
为认识中浅层油气成藏特征,在东营凹陷中浅层油气成藏地质研究基础上,利用二维模型模拟了不同断面形态的情况下,断层对中浅层石油运移和聚集的影响。研究结果表明:(1)
在幕式(非稳态)充注条件下,断层面的形态对中浅层石油的运移路径和方式构成重要的影响,S形断层面最有利于断层上、下盘砂层油的充注,这时油在砂层中的运移速率较大,而凹形断层面则有利于断层下盘砂层油的充注,凸形断层面有利于断层上盘砂层油的充注;(2)
越陡、弯度越少的断层面越有利于油的运移,即通常所认为的凸形断层面对油气运移起到发散作用,凹形断面起到油气运移汇集作用从模型试验中得到证实。

Abstract: On the basis of geological studies of hydrocarbon migration and
accumulation in the middle and shallow formations in Dongying depression, this
experiment models the influence of opening faults of different faultplane
shapes on petroleum migration and accumulation with a 2D model. The results are
as follows: (1) The faultplane shape has a great influence on the moving path
and pattern of petroleum in middle and shallow formations in impulsive
(unsteady) injection conditions. Sshaped faults are most favorable for the
petroleum infection of both upper and lower plate layers, and the oilmoving
speed is fast. Concave faults are favorable for the infection of lower sand
beds, and convex faults are favorable for the infection of upper sand beds, (2)
The more abrupt and less bended the faults are, the easier the migration of oil
is; that is to say, convex
faults play the role of divergence, while concave faults play the role of
convergence, which is well known, but has not been shown by a modeling
experiment.
Key words: faultplane shape; petroleum migration and accumulation; modeling

摘 要:
为达到在交易成本框架下分析厂商的技术创新行为,通过分析拍卖、免费发放以及按产量比例分配的3种排污权分配方式对污染治理技术创新的影响,结果表明,3种分配方式的创新激励并没有一致的大小关系,而是受污染物削减成本函数、厂商数目以及给定的技术模仿系数等因素的影响并建议在进行排污权分配时,根据我国国情,把几种分配方式结合起来,这可以使排污权交易不仅顺利进行,而且会更好的激励排污厂商进行污染治理技术创新。

Impact of Emission Permits Allocation
on Pollutant Abatement Technology Innovation

(College of Environmental Science and Engineering, Ocean University of China,
Qingdao 266003, China)
Abstract: One of the current models is extended to include transaction costs in
this paper. An analysis is made of the impact of the three tradable permits
allocation methods—auction, grandfathering and outputbased allocation—on the
incentives to innovate pollutant abatement technology. It is concluded that none
of the three allocation methods is definitely superior to the rest, and that a
firm's abatement cost, output market share and technology imitation level are
important factors influencing its incentives to innovate pollutant abatement
technology. Finally it is suggested that emission trading can not only be
successfully carried out, but it can also bring about better incentives to
innovation if the three allocation methods are well combined.

Abstract: In this paper an optimal filtering algorithm and an optimal smoothing
algorithm for the estimation of measurement noise are developed for systems with
multiplicative noise. They are developed on the condition that the
multiplicative noise is in the form of a general stochastic matrix and all the
multiplicative noise from each observation channel is correlated simultaneously.
These two algorithms are optimal in the sense of linear minimumvariance. Some
simulations have been provided to show the validity of these algorithms.

Abstract: Comparisons between the structure and properties of highstrength
polyethylene (HSPE) and common polyethylene(PE) monofilaments for fishing gear
have been made by differential scanning calorimetry(DSC), wide angle Xray
diffraction(WAXD) and scanning electron microscopy(SEM) etc.. The results
indicate that the HSPE monofilaments are 14.54% and 3.05% higher than the common
PE monofilaments in breaking strength and knot breaking strength, respectively,
while in percentage of breaking elongation the latter is 44.44% bigger than the
former. The HSPE monofilaments are 6.20% and 76.8% bigger than the common PE
monofilaments in crystallization and sonic velocity value, respectively. They
crystamine sizes of the HSPE monofilaments are slightly bigger than those of
the common PE monofilaments, while the unit cell parameters of the two are
approximately the same,
and the morphology of the HSPE monofilaments are of shishkebab and fibrous
compound structure. Owing to the increase of crystallization and the degree of
orientation, and the formation of this shishkebab and fibrous compound
structure, the tenacity of the HSPE monofilaments is improved.

Abstract: The cytology of the cross fertilization and the development of early
embryos of Chlamys farreri♀×C.nobilis♂ were investigated under fluorescent
microscopic observation with HOECHST33258 stained. The results showed that the
mature eggs of C.farreri were at prophase or metaphase of meiosisⅠ. Parts of
sperms
from C.nobilis could bind and penetrate into the eggs from C.farreri. With the
activation of these sperms, the eggs resumed their meiotic division and released
their first and second polar bodies successively. The male and female pronucleus
fused finally. Most hybrids could develop normally. However, distinct stunt and
asynchrony characterized the development of the hybrids, compared with the
control groups. This study primarily testified the feasibility of crossbreeding
between the two interspecific scallops.

Abstract: The conidia of Pseudomonas Y8.0 are mutagenized by NTG, Co60 and
UV.Chitosanaseproducing mutant of Pseudomonas Y8 are obtained by screening with
a method of transparent zones. The chitosanase activity is 3.0U/mL and raises 6
times. The method of UV is better than others. The cultural conditions of
chitosanase, produced by Pseudomonas Y8, are investigated. The optimal
conditions for chitosanase produced by Pseudomonas Y8 are as follows: pH 6.5,
temperature 32℃, Chitosan 3g/L, yeast extract 0.3%, and fermentation for 3 days.
Fe2+,Mg2+ can activate the Chitosanase's production, but Zn2+, Mn2+ inhibit it.

Abstract: Comparisons between the structure and properties of highstrength
polyethylene (HSPE) and common polyethylene(PE) monofilaments for fishing gear
have been made by differential scanning calorimetry(DSC), wide angle Xray
diffraction(WAXD) and scanning electron microscopy(SEM) etc.. The results
indicate that
the HSPE monofilaments are 14.54% and 3.05% higher than the common PE
monofilaments in breaking strength and knot breaking strength, respectively,
while in percentage of breaking elongation the latter is 44.44% bigger than the
former. The HSPE monofilaments are 6.20% and 76.8% bigger than the common PE
monofilaments in
crystallization and sonic velocity value, respectively. They crystamine sizes
of the HSPE monofilaments are slightly bigger than those of the common PE
monofilaments, while the unit cell parameters of the two are approximately the
same, and the morphology of the HSPE monofilaments are of shishkebab and
fibrous com
pound structure. Owing to the increase of crystallization and the degree of
orientation, and the formation of this shishkebab and fibrous compound
structure,the tenacity of the HSPE monofilaments is improved.

Abstract: Hydroxyethyl chitin is a water soluble chitin derivative which was
made by means of etherification of chitin. Ethylene chlorohydrin was used as an
etherification reagent in this study . Hydroxyethyl chitin showed an excellent
solubility in water. Three novel hydrogels based on Glycol chitin were obtained
by using different amounts of PTGE as crosslinking reagents under 50℃
respectively. The swelling behaviour, swelling kinetics of hydroxyethyl chitin
hydrogel and the effects of temperature, pH value on the swelling ratio of
hydrogels were st
udied. The results showed that the swelling ratio in acid buffer solution was
bigger than that in basic buffer solution, and it improved with the decrease of
pH value. The swelling ratio of hydrogel increased with the increase of
temperature from 25℃ to 50℃, and it increased sharply from 35℃ to 50℃. The
hydroxyethy l chitin hydrogels show good sensibility to temperature and pH
value.

摘 要:
为探讨海水水质监测的简便可行方法,对渤海、北黄海、胶州湾、东海、长江口、南海及珠江口几百个海水样品紫外扫描发现,不同海区海水紫外吸收约在200~220nm之间。其中渤海、北黄海与胶州湾海水样品在208~210nm之间,而东海、长江口、南海及珠江口水样在205nm附近。海水紫外吸收吸光度与高锰酸钾法测COD值之间具有良好的线性关系。所以提出了用紫外分光光度法测定海水COD值的方法,发现紫外分光光度法与碱性高锰酸钾法测定海水COD值无显著性差异,可以满足快速监测的需要。

Abstract: The ultraviolet absorption of thousands of seawater samples from the
Bohai Sea, the Northern Yellow Sea, the Jiaozhou Bay, the East China Sea, the
mouth of the Yangtse River,the South China Sea and the mouth of the Zhujiang
River was determined by ultraviolet spectrophotometry. The results show that all
the a
bsorption peaks appear between 200 and 220 nm. Or, to be more exact appear between
208 and 220 nm for samples from the Bohai Sea, the Northern Yellow Sea and the
Jiaozhou Bay, and at about 205 nm for samples from the other waters. It is found
that the results obtained by ultraviolet spectrophotometry and alkalescent
permanganate titration for determining COD have a good linear relation, which
indicates that the two methods have little difference in this regard. The method
for determining the COD of seawater by ultraviolet spectrophotometry is
introduced in the paper, which can meet the demands for rapid COD determination
in scientific researches.

内潮波主要导致相邻简正波间耦合;非线性内波包能够导致跨号甚至垮多号简正波间耦合。

Ocean Internal Waves in ASIAEX 2001 and the Numerical Simulation of Sound
Propagation

(Department of Physics, Ocean University of China, Qingdao 266071, China)
Abstract: The characters of ocean internal waves (IWs) are obtained by analyzing
the ASIAEX2001 temperature data. The M2 internal tide, internal solitary wave
packets with “periods”of 1030min, and a couple of internal solitary wave
packets are observed. The measured temperature data are used as input to the
enviro
nmental models for numerical simulation of sound propagation. Numerical
simulations are carried out for sound wave propagation which is perpendicular to
and parallel with the propagating IWs, respactively. For the former, it is shown
that the frequency spectra of the modal wave numbers and modal amplitudes are
consistent with those for the sound speed fluctuation caused by IWs. For the
later, it is shown that an internal tide causes adjacent (acoustic) mode
coupling, but non adjacent mode coupling can be caused by internal solitary wave
packets. In this paper, the fluctuation of acoustic signals caused by linear IWs
is also discussed. Two acoustic methods for monitoring ocean internal waves are
presented.

Abstract: The traditional color histogram contains the component of color but
lacks spatial information. To improve the performance of contentbased image
retrieval, spatial information is indispensable. An approach to partitionbased
color image retrieval is proposed in this paper. The images in the training set
are partitioned into size fixed cells and, from each cell, the local color
histogram as a color invariant feature is extracted. By clustering and coding,
the images in the database can be regarded as a combination of local color
features in certain spatial distribution. The effectiveness of this approach is
comfirmed by the experimental results.

Abstract: Based on field survey data, the hydrodynamical characteristics,
submarine topographic features, sediment types and stratum distribution of the
Guangli river mouth are obtained. The sediment source and erosionaccumulation
process are discussed through analyzing previous data and current sedimentary
characte
ristics. The results indicate that the sediment of the Guangli river mouth bar
came from the upriver Guangli river, the Zhimai River and Yihong River, while
the sediment of the Huanghe River produced an important effect on the mouth bar,
and the river mouth bar has entered an equilibrium phase. The result shows that
the hydrodynamic action on the northern side of the bar is stronger than on the
southern side, therefore a channel in the east by southwest by north direction
will be advisable.

Abstract: In this paper, the geological and sedimentary characters of ancient
gullies in the south slope of Chenjiazhuang heave in Jiyang Depression have been
studied based on the new three dimension seismic data and logging data collected
in Shengli Oil Field. The seismic and sedimentary faces of the three ancient
gullies in different structural stage and in different basin evolvement stage
are summarized. By combining sedimentary environment and sedimentary system in
the same period, the paper demonstrates the possible sedimentary phases in the
ancient gullies. At the early development stage of the boundary fault—Chennan
fault, the gullies were filled with Kongdian Formation and the forth sect of
Shahejie Formation sediment. The sediment in the gullies was coarse crumb sand
body or conglomerate of the root of fandelta with disorder laminate, different
amplitude
and short reflections. At the most active stage of the boundary fault, which corresponding
to the Denying Sags deep depressed stage, the gullies were filled with the
third and the second sect of Shapelier Formation. The Denying Sag was astarve
basin at this stage, so the front accumulate reflections are very developed in
the gullies with continuous reflection and large amplitude. The sedimentary
faces in gullies are coarse sand body of delta interbedded with fine sang body
of shallow lake. At the shrinkage stage of the Dongying Sag, the activity of
boundary fault was subdued. The gullies filled with riverdelta phase with the
strong, parallel and continuous reflections at this stage. As the cover layer of
the gullies, the upper sects of Dongying Formation are also strong, parallel and
continuous reflection. In the end, the paper appraises the oil accumulation
ability of the three ancient gullies. Reversedragging anticline developed in 3
gullies, front accumulation sand body, deeplake phase mud and shale may
compose the advantageous oil accumulation section.
