摘要：

富林洼陷是渤海湾盆地济阳坳陷沾化凹陷的一个次级构造单元,对富林洼陷进行地球化学分析和对比,研究油气运移成藏规律。表明,富林洼陷原油既有来自孤南洼陷古近系沙河街组三段的成熟油,又有分别来自富林洼陷中次洼和东次洼自身的中熟油和低熟油,主要以富林洼陷中次洼中熟油为主。油气运移的条件和油气运移的特征决定了油气藏的形成与分布。富林洼陷及其周边地区不整合面、断层以及各层系储集砂体的空间配置构成复杂的立体网络通道,决定了油气的运移,控制了油气分布。

Abstract:

Fulin sub-sag is a secondary structural unit in Zhanhua sag of Jiyang depression,Bohai Bay Basin. Geochemical analysis and oil-source correlation show that the sag not only contains mid-and low-mature oils from the central and eastern parts of the sub-sag,but also mature oil from the third member of the Paleogene Shahejie Formation in Gunan sag,in which the mid-mature oil is predominant.The conditions and characteristics of hydrocarbon migration determine the formation and distribution of oil and gas reservoirs.The complex pathway network consisting of unconformities and faults in Fulin sub-sag and its periphery as well as the spatial configuration of reservoir sandbodies in various strata controlled the migration and distribution of oil and gas.

Key words: source rock, faulted zone, unconformable surface, oil and gas pool, Jiyang Depression
