摘　　要：在对阳信洼陷油气成藏条件分析研究的基础上,以成藏动力系统理论为指导,对该区进行了成藏动力系统研究。将阳信洼陷划分为底部自源高压半封闭、下部自源—它源高压半封闭、中部自源—它源高压半封闭、上部自源—它源常压半封闭、顶部它源常压开放5个油气成藏动力系统,分析了各个系统的生、储、盖组合及圈闭特征和输导体系。底部自源高压半封闭和下部自源—它源高压半封闭2个系统是该区的重要油气成藏动力系统。成藏动力系统的输导体系类型多样,有断裂输导体系、火成岩输导体系、物性好的高孔渗岩层和不整合输导体系,它们对油气的运移和聚集起着重要作用。Based on the research of the conditions of petroleum accumulation in Yangxin sag and under the guidance of the theory of dynamic system of petroleum migration and accumulation,the dynamic systems of petroleum migration and accumulation in Yangxin sag arestudied. There are 5 dynamic systems that are divided in Yangxin sag,and the generation-reservoir-cap and trap assemblages of every system are analyzed,as well as its related sand transport systems.Research indicates that the bottom authigenic overpressure and semi-seal system, and the lower authigenic-allochthonous,overpressure and semi-seal system are the important dynamic systems of petroleum migration and accumulation in this area.
