应力驱动与油气运移势场的剖面研究

STUDY OF TECTONIC STRESS CONTROL OF OIL AND GAS MIGRATION IN SECTIONS

油气的生成运移和聚集是石油地质过程的主要组成部分，油气藏的形成是一个漫长的地质历史过程。本文以构造应力场是油气运移和聚集的主要驱动力为观点，对塔里木盆地北部地区的典型储油构造型式进行了剖面上运移势场的模拟计算，结果表明应力场低值区与运移场低值区相对应，并且运移势场低值区与油气藏对应很好。

The formation, migration and accumulation of oil and gas forms a most important subject in petroleum geology. The oil and gas accumulation is thought to be a long continued process in the past geologic time. It seems to the authors that the action of tectonic stress may create the most important conditions to drive the migration and accumulation of oil and gas. The states of migration potentials have been simulated and calculated for a few typical sections in the northern Tarim Basin. The results obtained show that the low stress field corresponds to the areas of low migration potentials, where oil and gas pools occur.
