摘　　要：构造应力在油气藏生成及分布过程中发挥了重要作用。一方面构造应力通过产生机械能及力化学作用促进了干酪根热降解 ,促进了油气的生成。另一方面构造应力通过影响油气的流体势 ,使油气从高势区向低势区运移 ,并同时使油气得到富集。此外 ,构造应力还为油气聚集成藏提供了场所 ,并对其分布有很强的控制作用。Tectonic stress plays an important role in the process of oil gas pool formation and distribution.On one hand,tectonic stress produces mechanical energy and strength chemical action which improve the thermal degredation of kerogen and oil generation;on the other hand,tectonic stress can influence the fluid potential which results in oil and gas migration from higher potential zone to lower potential zone.In addition,the stress also produces tectonic traps for oil and gas accumulation and enrichment and controlls their distribution.
