摘　　要：侏罗系J1s2是莫西庄油田岩性圈闭的重要储油层系。利用测井解释、沉积相分析、油源对比等手段,对莫西庄地区J1s2油气藏形成条件进行了研究,认为J1s2油气成藏与分布的主要控制因素为隔、夹层分布与储层物性变化带。二叠系烃源岩是莫西庄地区油气的主要来源,三角洲前缘水下分支河道和河口坝砂体是J1s2的主要储集砂体,J1s1泥岩、J1s12与J1s22上下砂岩层之间的隔夹层泥岩是油气成藏的区域、局部盖层。Member 2 of Sangonghe formation(J1s2)in Jurassic is an important reservoir rocks of lithologic trap in Moxizhuang Oilfield.Hydrocarbon accumulation conditions of Sangonghe reservoir in Moxizhuang area are researched by the technology of oil sources correlation,3-D structure interpretation,well log constrained wave impedance lithology inversion and 3-D geological modeling,it is concluded that source-reservoir-cap rock association and lithologic trap are two main control factors for hydrocarbon accumulation and distribution.Permian hydrocarbon source rocks are main sources in Moxizhuang area,and sand body of underwater channel of delta front and mouth bar are main reservoir rocks.Mudstone in Sangonghe member 1 is the regional cap rocks while the mudstone between top and bottom sand body in Sangonghe member 2 is the local cap rocks.
