摘　　要：本文总结了地应力对油气生成、运移、聚集等方面的影响规律,并结合梁家楼油田地质资料及其地应力演化规律,通过对研究区的应力演化分析,得出梁家楼油田在其应力演化过程中,其演化史控制了现今油田含油区块展布。为油气运移中,地应力是油气运移的动力提供了有力证据。地应力的集中可致地质体形变与体积变形,地应力作用下地质体体积的变化,改变了施加在流体上的压力,流体在势差下发生流动;地应力作用下形成的断层和裂缝为油气运移提供了运移通道,同时形成的各种构造圈闭,为油气聚集提供了良好场所。This paper summarized the law of the influence of In-Situ Stress on the hydrocarbon generation,migration,accumulation.Combining geological data,in the evolution process of In-Situ stress,the history of evolution controlled the current distribution of oil fields,proving that the In-Situ Stress is the main force for oil-gas migration effectively.The concentration of In-Situ Stress resulted in the deformation of the geological body,and the geological body＇s volume change,fluid flows under the potential difference.The faults and cracks resulting from In-Situ Stress provides a migration pathway for the oil-gas migration,while the formation of a variety of structural traps provides a good place for oil and gas gathering.
