摘　　要： 为了研究凹陷南屯组和铜钵庙组沉积特征，充分收集岩心、地震数据、试油、录井等资料，利用精细地震解释技术进行沉积体系研究。通过利用层序地层学理论，基于构造地质学，同时结合现场的相关测井、三维地震等资料对乌尔逊凹陷储层进行综合研究。研究期间结合前人研究成果，对本区的有利油气区展开预测。达到对今后开发指导的作用。 乌尔逊凹陷南屯组和铜钵庙组界面属于不整合接触。通过分析地层特征，以沉积地层的时间单元为研究对象的，明确研究区的构造特征。研究表明乌尔逊凹陷主要有两套构造层组成，构造层上部为断坳构造层，构造层下部为断陷构造层。乌尔逊凹陷构造复杂，强烈的构造运动，造成断裂系统多样性，形成极其特别的断层样式。 明确了构造特征，再通过凹陷内岩心观察,结合测井资料、古生物特征、地震资料解释等研究,明确了乌尔逊凹陷从南屯组到铜钵庙组沉积相类型主要有冲积扇、扇三角洲、河流、三角洲、湖泊等5种相。通过研究单井相、剖面相、平面相明确凹陷的沉积体系特征。对主要研究区南屯组和铜钵庙全方位分析，最终确定了沉积相展布和沉积相类型。 通过分析构造圈闭，生油与储油条件对各个主力油层组成藏进行研究。为预测有利储层研究打好基础。分析构造与储层特征，落实有力圈闭位置，储层油藏情况。详细分析工区的生、储、盖、运、圈、保油藏要素，沉积特征等地质因素。最终确立了研究区内构造带、斜坡带和洼槽为主要的产能区。 In order to Nantun formation and Tongbomiao formation sedimentary characteristics ofthe depression, the full collection of core, seismic data, logging, oil test data, to studysedimentary system by using the precise seismic interpretation technique. By using the theoryof sequence stratigraphy, based on structural geology, logging, and combining with the relatedfield of3D seismic data on the WuErxun depression reservoir comprehensive research.During the study period, based on previous research results, the favorable oil and gas zone onthe area of the development of forecasts. To the future development of guidance role. Belongs to the unconformity contact Nantun formation and Tongbomiao formationinterface WuErxun sag. Through the analysis of the stratigraphic characteristics, sedimentarystrata in time unit as the research object, the structure characteristics of the study area.Research shows that WuErxun depression are mainly composed of two sets of structural layer,structure layer upper faulted depression tectonic layer, structure layer for the lower part of riftstructure. WuErxun depression complicated structure, strong tectonic movement, resulting infracture system diversity, form a very special fault style. The structure characteristic, again through the depression of core observation, loggingdata, paleontology, interpretation of seismic data, the WuErxun depression Nantun group fromTongbomiao formation sedimentary facies types are mainly alluvial fan, fan delta, fluvial,Delta, lake and other5kinds of phase. Sedimentary system of single well facies, profile,plane clear depression. Analysis on the main research area of Nantun group and Tongbomiaoomni-directional, and ultimately determine the types of sedimentary facies and sedimentaryfacies. Through the analysis of structural traps, hydrocarbon generation and storage conditionson the various components of the main reservoir reservoir. For the prediction of favorablereservoir to lay a good foundation. Analysis of structure and reservoir characterist
