摘要
总结了构造应力对油气生成、运移、聚集及分布等方面的影响。指出构造应力与油气成藏关系密切,其不仅能形成断层和裂缝等油气运移通道,还能形成各种构造圈闭,同时也可直接引发油气运移,是油气运移的主要驱动力;构造应力与孔隙流体压力有相关性,油气从强压应力区向张应力区运移,张应力区是油气的最佳聚集区;构造应力对油气藏的形成既可以起到积极作用,也可以对其起破坏作用;构造应力还可为有机质向烃类转化提供能量。
This paper discusses the influence of structural stress on the generation, migration, accumulation and distribution of petroleum. It points out that structural stress can result in faults, fractures and many kinds of structural traps, and is an important driving force for petroleum migration. There is a close relationship between structural stress and fluid pressure, and the tensional stress area is favorable to the accumulation of petroleum. Structural stress can also provide energy for the transformation from organic matter to oil and gas.
