摘　　要：留路断层是留北东部地区主要的油源断层。为研究断层两侧油气成藏规律及差异性,以断裂控烃、控藏理论为指导,利用三维地质建模恢复断层形态,在分析断层两盘裂缝发育程度、断层与圈闭的配置关系和断层活动性的基础上,研究留路断层对新近系油藏发育程度、部位、层位和规模的控制作用。研究结果表明:留路断层断面形态控制油藏富集区域,油藏集中在断层走向转折附近;断层带结构分带性及断层与圈闭的产状配置关系是留路断层下降盘油气富集差异的主要原因;断层活动性控制油气富集与分散,断层活动性强,油气富集规模大、油藏赋存层系多。Liulu Fault is the main oil-source fault in East Liubei. In order to figure out the petroleum accumulating laws and difference along the fault,guided by the theories of hydrocarbon and reservoir controlled by the fault,with the help of the resorted fault configurations by 3D geological modeling,on the bases of the following analyses：fracture developed degree for the two walls of the fault,matched relationships between the fault and traps,and the fault activity,the controlling actions of Liulu Fault on the developed degree,position,layer and size of Neogene oil reservoirs were researched. The achievements show that the configurations of Liubei Fault planes control the enriched region of the reservoirs,the reservoirs are located near the turning point of the fault strikes; the zonality of the fault belt structures and matched relationships between the fault and trap occurrences are the main reasons for the hydrocarbon accumulation difference of the lower wall of Liulu Fault; the fault activity dominates the enrichment and dispersion of the oil and gas,the stronger the activity is,the bigger the accumulation size and the more the enriched series of the strata will be.
