焉耆盆地是新疆地区一个侏罗系含油气盆地。与断层有关的圈闭已成为焉耆盆地未来油气勘探的重要目标。运用断层涂抹系数,结合断层活动历史研究了焉耆盆地博湖坳陷几条重要断层的封闭性,并分析了它们对油气运移和聚集的作用,为焉耆盆地油气成藏机理研究和断层圈闭评价提供了依据。
Yanqi Basin is a Jurassic petroliferous basin in Xinjiang. Fault-related traps have become an important target of future oil and gas exploration in the Yanqi Basin. Based on the fault smearing coefficient and the history of fault activity, the sequestration of several important faults in the Boqi depression in the Yanqi Basin was studied, and their effects on hydrocarbon migration and accumulation were analyzed. The study is of hydrocarbon accumulation mechanism and fault trap in the Yanqi Basin Evaluation provides the basis.
