摘要:

黄骅坳陷孔南地区新生代盆地演化经历了断陷期、断坳期及坳陷期。盆地内部发育复杂断裂系统,根据断层活动特征可以分为沧东伸展断裂系统与徐西右旋走滑断裂系统。沧东断层剖面上具有铲式正断层特征,向深部滑脱,控制了孔南地区的构造变形;徐西断层可以看作是其上盘上的次级断层。在孔店组沉积期,沧东断层与徐西断层均表现出伸展正断层的特征,控制了其上盘孔店组沉积。在沙河街组三段沉积期,受基底断层右旋走滑影响,徐西断层及其上盘分支断层表现出右旋走滑特征。在伸展与走滑的共同作用下,在孔南地区中北部聚集了丰富的油气。

Abstract:

Kongnan area of Huanghua depression has experienced rift stage, faultedsag stage and sag stage with complex fault systems. Based on the activity, the fault systems can be divided into two types: The Cangdong extension fault system and Xuxi rightlateral strike-slip fault system. Cangdong fault is a listric normal fault slipping into the deep crust and controlling the global deformation of Kongnan area. The Xuxi fault can be considered as a secondary fault in the hanging wall of Cangdong fault. In the stage of Kongdian Formation depositing, the two faults performed as normal faults, cocontrolling the distribution of Kongdian Formation. When the 3rd Member of Shahejie Formation was depositing,  Xuxi fault system performed as a right-lateral strike-slip fault which was influenced by the pre-existed basement fault. With the control of the process of extension and strike-slip,abundant hydrocarbon had accumulated in the centralnorth part  of Kongnan area.

Key words:  Huanghua depression, Kongnan area, Cenozoic, fault system, extension and strike-slip
