摘　　要：南阳凹陷构造演化主要受边界断层及内部各级断层的控制,边界断层的构造特征及活动性表现为沿走向的分区性及其构造沉降中心迁移变化,形成现今的“3洼2隆1斜坡”的构造格局,古近系整体表现为“南断北超”的被断层复杂化了的半地堑型断陷,新近系总体为沉降差异较小的坳陷结构。通过对凹陷构造及其控藏作用分析,认为不同时期构造活动进一步控制了烃源岩、储集岩和圈闭的形成与发展,而且构造活动的合理序次使圈闭能有效捕获油气。The structural evolution of Nanyang depression is mainly controlled by the boundary fault and the fault at all levels.The structural characteristics and activity of the boundary fault are the zoning and the change of the construction settlement center along the direction,and the structure pattern of the present“3-wa 2-long 1 slope”is formed.The overall performance of the Paleogene is a half-graben-type fault which is complicated by the fault of the“North and South of the South”,and the recent system is the depression structure with small settlement difference.In this paper,the formation and development of source rock,rock-rock and trap are further controlled through the analysis of the depression structure and its control and storage.Effectively capture oil and gas.
