南堡凹陷断裂带构造演化及成藏条件分析

Tectonic Evolution of Nanpu Fault Zone and Analysis of Geological Conditions for the Formation

论述了南堡断裂构造带的构造特征，利用平衡剖面技术平衡复原了过去该构造带的主干剖面，结合地震剖面反射结构及全区总体构造格局资料，分析了该构造带的演化历史，探讨了其形成机制。从生储盖组合、构造圈闭与排烃期的配置以及油气运移通道等方面论述了该构造带与油气的关系。

This paper describes the geometry of Nanpu fault zone and restores a main seismic profile across the belt by using balanced cross-section technique for extensional area. On the basis of reflection configuration, overall structural framework and the balanced ctoss-section, the author discusses the tectonic evolution and forming mechanisms of the belt. This paper also illustrates the relationship with hydrocarbons based on source-reservoir-seal as-semblage, forming time of structural traps and hydrocarboa erpulsion, and hydrocarbon migration paths.
