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 analysis of oil and gas accumulation conditions in Yangxin Sag, taking the theory of reservoir dynamical system as a guide, the dynamic system of reservoir formation was studied. The Yangxin depression is divided into bottom semi-closed high-pressure bottom and bottom self-source high-pressure semi-closed and middle self-source high-pressure semi-closed and upper self-source semi- Open up five oil and gas accumulation dynamic system, analysis of the various systems of raw, storage, cover combination and trap characteristics and transmission system. Bottom self-source high-pressure semi-closed and lower self-source - its source high-pressure and semi-closed two systems are important oil and gas accumulation dynamic systems in this area. There are many types of transport systems for reservoir dynamical systems, such as fault fracture system, igneous conductivity system, high porosity and permeability aquifer and unconformity transport system, which play an important role in hydrocarbon migration and accumulation.
