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。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.
