摘　　要：埕海断坡区是歧口凹陷滩海区重要的油气勘探区域,多年来受地表、地下复杂地质条件制约,勘探工作起步较晚,基础研究相对薄弱,油气富集规律尚欠缺系统的分析研究.以埕海断坡区古近系沙河街组、东营组为研究重点,对该区油源条件、生储盖组合及储层、圈闭等油气成藏因素的地质特征加以分析,进一步总结出基岩潜山背景,湖盆演化阶段,沉积微相展布是埕海断坡区油气富集的主控因素.These yeares,Chenghai fault-slope of Qikou depression has become one of the most important exploration tracts in Dagang oilfield.However,because of late exploration works and relatively weaking in fundamental research for complex geological condition in both suface and subsurface,the hydrocarbon accumulation conditions and the main controlling factors in this district were still lack of system analysis.this paper started from studying on hydrocarbon accumulation conditions of Shahejie and Dongying foramtion,by analysising the oil sources、source-reservoir-cap assemblage and reservoir characteristics、traps in this region,then the paper summarized that the burial hill background,basin evolution and microfacies are main controlling factors for hydrocarbon accumulation in chenghai fault slope.
