摘要
分析了扶杨油层断裂系统的发育演化对油气运移成藏的控制作用,并对扶杨油层的构造演化史进行了刻画。扶杨油层发育的坳陷期以伸展作用为主,姚家组、嫩江组、明水组期间断裂活动最为强烈,发育了大量贯穿泉头组地层与靑一段地层的油源断层,形成了掀斜断块与阶梯状断块,对油气的成藏起到控制作用。断裂的形成演化控制圈闭的形成时期、发育类型及展布方位。长期活动的断裂是扶杨油层主要的油源断层类型,围绕富烃洼陷发育受油源断层控制的掀斜断块圈闭以及阶梯状断块圈闭是油气运聚成藏的有利目标区。
Analysis the influence of Fuyang reservoir fracture system to oil migration and accumulation.Map the tectonic evolution of Fuyang reservoir,the main tectonic stress of the era that Fuyang reservoirdeveloped is extension stress,FuYang reservoir developed lots of large faults at Yaojia formation,Nenjiang formation and Mingshui formation,some faults through QIingYI layer and QuanTou formation,these faults play a role in migrating oil.Formulating titled blocks and step-like blocks,which control oilmigration and accumulation.The formation and evolution of fault control the era of fault,developed typeand distribution location.Long time activated faults is main source fault of Fuyang reservoir.Aroundsource-rock,the basement block traps,tilted block and step-like blocks with controlled by source faultswere favorable areas of hydrocarbon migration and accumulation.
