义和庄地区地层油气藏分布特征及控制因素

义和庄凸起是一个在对基底构造层长期改造基础上发展起来的大型正向构造单元，基底地层长期遭受风化剥蚀，沉积盖层超覆其上。受区域构造运动影响，义和庄凸起及其北部斜坡带发育多期区域不整合，地层超覆、剥蚀现象十分普遍。义和庄地区地层接触关系复杂，有利于各类地层圈闭的形成，是济阳坳陷地层油气藏最发育的油气聚集带之一。超覆油气藏、不整合油气藏、潜山油气藏具有不同的形成条件与控制因素，分别发育于不同的层系与区带，其分布规律主要受区域构造运动、油源条件、疏导体系等因素控制。区域构造运动形成的不整合面上、下分别发育超覆圈闭和不整合圈闭，基底反向正断层控制潜山圈闭的分布。车西、大王北、郭局子、四扣等生油洼陷为义和庄地区提供了丰富的油气来源，断层、不整合面与渗透性地层构成的立体网络式输导体系有利于油气在各类地层圈闭中聚集成藏。

Distribution characteristics and controlling factors of stratigraphic reservoirs in Yihezhuang Area

Yihezhuang Salient is a large positive structural unit which has developed on the basis of reconstructing to the basement strata in a long time.The basement strata have a long-term process of weathering and denudating,and the sedimentary cover strata overlaped on it.Owing to the regional tectonic movements,multi-stage unconformities formed in Yihezhuang Salient and its northern slope belt and overlaping and denudating are universal.There are complex contacting relationships within different strata,so Yihezh...
