摘要
通过恢复梨树凹陷构造演化历史,对本区控制断陷演化的主要断裂的性质、成因、现今特征、发育历史进行分析,总结出断裂活动的5种模式。结合本区石油地质特征,解剖已知的油气藏和非油气藏,从断裂与油气生、运、聚、保等方面的关系,明确了断裂是控制油气成藏的主要因素,它不仅决定了生烃凹陷的展布和规模,而且常成为连结油源与圈闭的运移通道。断裂控制着圈闭的形成与分布,也是油气藏保存的重要的构造因素。总结出断裂控油气的4种模式。
Five kinds of fault activity model are summedup by recovering the tectonic developing history of Lishu depression and by studying the main controling fault's nature,formation causes,present property as well as evolutive history, through analysing oil and gas accumulation and non-oil and gas accumulation,as well as the relation of fault and petroleum generating, migrating,accumulating.It is concluded that fault is the main cause for controling oil and gas accumulation.The fault not only decides oil-generating depression scale and distribution,but also control the trap's forming,and the distribution fault also decides the oil and gas accumulation preservation.
