摘要: 分析了东濮凹陷的断裂系统及其活动性,研究了断裂系统内部断层间及断裂系统之间的位移传递方式及相应的变换构造类型。研究结果表明,断层间位移的传递方式有传递式、接力式、消长式和消减式4种类型,分别形成了传递断层和楔状断阶、走向斜坡和地垒凸起、中央斜向背斜、消减斜坡和断鼻等变换构造。东濮凹陷不同时期形成的变换构造,在近东西方向上相互联接形成变换构造带。这些变换构造带在平面上将东濮凹陷分隔成具有不同构造、沉积特征的区段;在垂向上,不同时期形成的变换构造发生叠加、改造和迁移,从而对沉积起控制作用,有利于隐蔽油气藏的形成。

Abstract: The fault systems and the fault evolutions were analyzed in the Dongpu Sag. The transfer ways of displacement and their corresponding transfer structures among faults within each fault system and among the fault systems were discussed. Four kinds of transfer ways of displacements were determined, including transformation, relaying, growth and decline, and simple decline. The way of transformation resulted in the transfer faults and wedge-shaped fault steps. The way of relaying resulted in the strike slopes and horsts. The way of growth and decline resulted in the central oblique anticlines. The way of simple decline formed decline slopes and fault noses. The transfer structures formed in different time were connected to form transfer structure belts and made the sag in segmentation. The superposition, reconstruction and migration of the transfer structures were closely related to sedimentation and favorable to generation of subtle reservoirs.

Key words: Dongpu Sag, rift basin, fault system, structural style, tectonic evolution
