摘要: 对于不同产状的断裂,其油气成藏控制机理与结果的差异很大。福山凹陷主体地区发育深层反向和浅层顺向两大断裂系统。前者形成时间早,活动性差,断距大小适合,有利于形成多种圈闭和对油气的遮挡成藏,控制了福山凹陷绝大多数油气藏的形成与分布;后者形成时间晚,长期多期活动,断层遮挡油柱高度小,不利于油气的聚集和保存。深层反向断裂控制的油气藏位于断裂下盘,浅层顺向断裂控制的油气藏位于断裂上盘,油气主要富集在深层反向断裂控制的下盘圈闭中。

Abstract: The faults of different occurrence have differential oil-gas reservoir controlling mechanisms.There are two kinds of fault systems including deep antithetic fault system and shallow consequent fault system in Fushan Depression.The deep antithetic fault system was favorable to form various kinds of traps and control the most petroleum accumulation distribution in Fushan Depression,because of its early occurrence,short activity time and proper fault throw.The shallow consequent faults were unfavorable to the petroleum accumulation and preservation.The oil-gas reservoir controlled by the deep antithetic fault system was located on the down block of antithetic fault.The oil-gas reservoir controlled by the shallow consequent fault was located on the upper block of consequent fault.Oil and gas were mainly accumulated in the down block traps of the deep antithetic fault system.

Key words: Hainan area, Fushan Depression, consequent fault, antithetic fault, reservoir controlling mechanism, fault trap, petroleum accumulation
