摘　　要：渤海湾盆地济阳坳陷陈家庄凸起东段北斜坡带的油源主要来自沾化凹陷,烃源岩主要发育在渤南、孤南、富林洼陷的沙四段、沙三段和沙一段,其中沙三段时期为典型的淡—微咸水还原的湖泊沉积环境,烃源岩有机质的母质来源主要以水生浮游动植物为主。烃源岩特征分析及油源对比结果表明,垦68、垦69井的原油主要来自于渤南洼陷的沙三段烃源岩,油气主要通过断层、砂体、不整合面以及由它们组成的复合型运移通道运聚到盆地边缘圈闭成藏。The First, Third and Fourth Members of the Shahejie Formation in the Bonan, Gu＇ nan and Fulin Subsags are the main source rocks of the reservoir in the northern slope of the Eastern Chenjiazhuang Uplift, the Jiyang Depression, the Bohai Bay Basin. By the analysis of source rock characteristics and oil-source rock correlation, the oil of the Ken68 and Ken69 wells are mainly from the Third Member of the Shanhejie Formation in the Bonan Subsag. The faults, sandbodies, unconformable surfaces and complex channels made up of faults, sandbodies, unconformable surfaces are the main migration pathways for oil and gas.
