Analysis of petroleum geology , reservoir types and distribution in lujiapu depression indicates that : the forming and distribution of reservoirs had been controlled by source area , source - reservoir relationship , petrophysical characteristics , sedimentary facies and secondary structure , and oil is most abundant in reservoirs around hydrocarbon kitchen ; the upper member of jiufutang formation which was entrained or embedded in the main oil source layer has well developed reservoir and good petrophysical property and is the principle oil - bearing interval ; the mid - fan and fan delta front of nearshore submarine fan is the most favorite facies ; the steep slope of the depression mainly consists of structural reservoirs , the slope belt mainly consists of structural - lithologic and updip pinchout reservoirs , the depressed belt mainly consists of lenticular lithologic reservoirs 摘要对陆家堡凹陷油藏形成的石油地质条件、已知油藏类型及分布的分析认为：生油区、生储配置关系、储集物性、沉积相带和二级构造带控制了油藏的形成和展布，其中围绕生油洼陷的油藏含油最丰富；夹持或嵌入主要生油层中，储层发育、储集物性又相对较好的九佛堂组上段是主要含油层段；近岸水下扇的扇中和扇三角洲前缘是最有利的相带：凹陷的陡坡带以构造油藏为主，斜坡带以构造岩性及储层上倾尖灭油藏为主，深陷带主要为透镜状岩性油藏。

From macro to micro and from qualitative to quantitative evaluation , this paper , applicating the theory and technological method of sequence stratigraphy , seismic stratigraphy - , reservoir sedimentology , combining with multispecialty and mutisubject theory that used geology , log , seismic , mathematics and earth physics and basing on synthetic application of regional geology , core , log , seismic and petrophysical property data , has studied the inner structure and characteristic of sequence , system tract and depositional system . combining with high resolution seismic data and log data , this paper makes a profound analysis of the space pattern and reservoir predictability of depositional system on oil and gas pools of honghaoersute sag 本文采取从宏观到微观，从定性到定量的研究思路，应用层序地层学、地震地层学、储层沉积学的理论和技术方法，结合区域地质、岩芯、测井、地震、物性资料，采用多专业、多学科理论和方法相结合。阐明层序、体系域和沉积体系的内部构成及其特征，与高分辨地震资料和测井资料的处理技术相结合，深入解剖洪浩尔舒特凹陷油气藏成藏组合的沉积体系空间配置、储层预测，在等时地层框架内对含油层段( k _ 1ba组、 k _ 1bt ~ 1及k _ 1bt ~ 2段)进行精细解剖，有目的地寻找以地层、岩性圈闭为主的隐蔽油气藏。

On the basis of previous research works , new exploration wells , new appraisal wells and 3d seismic material are added to new research work in which rock and mineral , sedimentary facies and oil bearing characters are studied deeply by employing the methods of petroleum geology , sedimentary geology and reservoir geology . the results of reservoir prediction on fluvial sandbody in the upper of formation of guantao group obtained by using coherent analysis and acoustical impedance inversion bring good effect to the exploration and development of chengdao oilfield 本文在以往工作的基础上，补充新钻探井、评价井和三维地震资料，运用石油地质学、沉积地质学、储层地质学等原理方法，对埕岛油田主力含油层系馆上段地层的岩矿、沉积相及油气富集特征进行了深入的研究，对馆上段河流相砂体进行了以测井约束地震反演为主的储层预测研究，研究成果为继续开展埕岛油田的勘探开发提供了重要依据。

The later migration - accumulating pools of hydrocarbon includes types es4 and es3 ; the vertical migration - accumulating pools contain hydrocarbon types es3 and es4 . reservoirs here are distributed along the fault zone and the southern slope of the bonan depression . using the above accumulated data , this study can be used as a basis for new explorative targets in three sand deposits to the north of this study area , providing some likelihood of exploration success 含油面积0 . 7km ~ 2 ，地质储量122 . 5万吨，含油层系沙三中，该块的发现是对垦西地区北部断坡带勘探取得了的新突破，根据本课题研究认为北部断坡带上的油藏主要沿斜坡呈带状分布的特征，提出了下一步的勘探目标，对北部三个砂体进行描述，争取有新突破。
