摘要(Abstract)：

民东地区是吉林油田低渗油藏效益储量提交的重点区块,成藏条件、成藏过程和成藏特征认识不充分。以新民油田350口开发井、民东地区82口探井、评价井和长春岭气田30口探井资料为基础,根据成藏条件评价和成藏过程解剖,揭示民东地区的油气差异成藏特征和主控因素,并进行现场实践。结果表明:新民、民东和长春岭地区油气来源具有差异性,造成沿江一带差异成藏;研究区成藏经历"沿源断裂垂向倒灌—沿断砂输导体侧向长距离运移—沿断裂垂向运移—构造脊圈闭聚集"的过程。断裂控制油气的运聚、成藏及分布,圈闭条件不足是造成油气过路的主因,它们与供烃条件共同耦合,造成新民、民东、长春岭地区在含油气程度上的差异。复查T29、T24老井试油及3处剩余出油点,对完善民东地区及沿江一带的成藏规律具有指导意义。
