摘　　要：为了研究断裂和不整合面配合在油气成藏与分布中的作用,在断裂和不整合面内部结构及输导油气特征基础上,采用断裂与沿不整合运移油气之间关系分析的方法,分析断裂沿不整合面侧向运移油气的聚集作用.结果表明:输导断裂对沿不整合面侧向运移油气的输导作用主要表现:改变运移路径和同层或跨层侧向连接输导作用.封闭断裂对沿不整合面侧向运移油气的聚集作用主要表现:形成断层遮挡型油气藏和反向断裂较顺向断裂更易形成油气藏.该研究为断裂沿不整合面侧向运移聚集的油气勘探开发提供指导.To study role of matching between faults and unconformity surface in oil-gas accumulation and distribution,based on the study of interior structure of fault and unconformity and their tram sporting oil-gas characteristics,we studied the role of faults in the accumulation of oil-gas migrating laterally through unconformity surface and oil-gas migration through unconformity surface and the result indicates flat role of trans porting faults to transporting of oil-gas migrating through unconformity surface has the following aspects,transporting changing oil-gas migration pathway and transporting countering the same layer of different layers.The role of sealed faults in the accumulation of oil-gas migrating through unconformity surface has the following aspects and forming oil-gas reservoirs sealed by faults;oil-gas reservoirs sealed by transude faults is easier flan oil-gas reservoirs sealed by cissoids faults.The research results can provide guidance for exploration and development of oil and gas which migration and accumulation down the side direction of the unconformity surface.
