从地震看重力侧向滑动构造与油气——兼论马西逆同生断层不是反转构造
|
摘要
重力构造作用分为侧向运动和垂向运动两大类。以渤海湾盆地及准噶尔盆地中的构造为实例,介绍了重力侧向滑动的六种构造样式,包括滑动断阶、逆牵引背斜、地层补偿堑背斜、滑落背斜、滑覆构造(逆同生断层)、推滑覆构造等。对其形成背景和形成机制逐一进行了分析,指明了这些构造的含油气潜力。这六种构造样式均可形成有利的油气圈闭,在勘探中应予以足够的重视。特别指出冀中坳陷马西逆同生断层不属于反转构造,而是由重力作用所产生的滑动推挤所致,为一典型的滑覆构造。
Gravity sliding can be divided into two sorts, the lateral and the vertical. Instanced by the sliding struc- tures developed in Bohaiwan and Junggar basins, six types of lateral gravitational sliding structures are introduced, which includes a sliding fault step, an inverse drag anticline, a stratigraphic compensating graben-like anticline, a slide-fall anticline, a sliding overthrust structure (i.e. inversed contemporaneous fault), and a sliding nappe. Their forming origin and mechanics are analyzed. All of these structures can be favorable hydrocarbon-bearing traps. It is suggested that a great attention should be paid to them in exploration. It is specially analyzed and indicated that the Maxi fault developed in Jizhong Depression is a typical sliding nappe, instead of a reversed fault, resulted from lateral compression of gravitational sliding movement.racrystalline pores and intracrystalline solution pores are com- mon.
