摘　　要：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 one of Jurassic petroliferous basins in Xinjiang region,western China.To find out traps related to faults is an important target for petroleum exploration in next few years.Applying fault daubing technique integrated with the history of faulting move-ment,this paper analyzed the sealing effects of a few major faults in Bohu depression of Yanqi basin,as well as their effects on petroleum mi-gration and accumulation.This provides valuable basis for study of hydrocarbon reservoir mechanism and evaluation of fault closure in Yanqi basin.
