摘　　要：辽河盆地是形成于中新生代的裂谷型盆地,断裂活动是盆地的主要构造运动形式.研究了该盆地曙一区断裂系统的演化史,分析了断层在超稠油成藏过程中的作用.认为断层一方面起遮挡作用,形成兴隆台油层的断层遮挡型油气藏;另一方面,断层在破坏原生油藏的同时起到油气运移通道的作用,油气二次运移,形成馆陶油层的次生油气藏.Liaohe Basin is a rifted basin formed in the middle Cenozoic,faulting was the main tectonic movement of the basin.Through the research of the evolution history of rift system of Shu 1 Block of this basin and the analysis of the effect of fault on the process of super heavy-oil reservoir forming,it is believed that,on the one hand,fault played the role of the barrier bed,forming fault screened hydrocasbon reservoir of Xinglongtai oil formation;on the other hand,at the time of destroying primary reservoir,the fault had played the role of oil and gas migration channel simultaneously;after secondary migration of oil and gas,there developed Guantao oil Formation secondary hydrocarbon reservoir.
