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 formation and distribution of oil and gas reservoirs. On the one hand, tectonic stress promotes the thermal degradation of kerogen through the generation of mechanical energy and chemical action, and promotes the formation of oil and gas. On the other hand, the tectonic stress can affect the fluid potential of oil and gas to transport oil and gas from the high potential area to the low potential area, and at the same time enrich the oil and gas. In addition, tectonic stress also provides a place for hydrocarbon accumulation and accumulation, and has a strong control over its distribution.
