摘要

以构造地质学和石油地质学基础理论为指导,探讨胡庆油田北东向反向正断层的形成机理与油气聚集的关系。研究认为,北北东向反向正断层的形成受北东—南西向张应力及右旋剪切力控制,反向正断层的走向与张应力方向基本垂直;反向正断层的相对挤压区有利于油气聚集,油气主要分布在断层弧形内侧相对应力集中区和几条断层组成的向油源区敞开的断块区。

Abstract

Guided by the basic theories of tectonic geology and

petroleum geology ,this paper discusses the relationship of oil and

gas accumulation and formation mechanism of east-north

antithetic normal faults. This study shows that the formation of

antithetic normal fault is controlled by NE—WS strike tensile stress

and dextral shear stress and the strike is nearly vertical to the

tensile stress. The relative compression area of antithetic normal

faults is advantageous to oil and gas gathering. The oil and gas

accumulation distributes mainly inside of major faults arc area

and fault zone opening to oil origin which was formed by several

fault.
