摘　　要：从研究朝阳沟阶地长10区块油气聚集特征出发,通过研究其成藏条件及主干断层各时期的发育特点,系统分析了油源断层和断裂密集带对油气聚集的作用机理。长10区块在明水组末期发生大规模断层活动,受反转的影响,断裂密集带总体呈背斜形态,形成朝阳沟阶地和长春岭背斜带。三肇凹陷生成的油气在超压作用下也于明水组末期沿油源断层下排到扶余油层,后沿河道砂体和断裂密集带匹配做侧向运移到长10区块,形成油气运移的通道,构成扶余油层主要富油气构造背景。According to the oil and gas accumulation characteristic from Chaoyanggou terrace Chang10 Block,through studying the accumulation conditions and major fault development characteristics of each period,system analysis the mechanism of oil source faults and fault concentration belt to oil accumulation.In the end of MingShui have happened to the large-scale fault activity in Chang10 block.By the influence of reversal,fault concentration belt have generally been anticline form,forming Chaoyanggou terrace and Changchunling anticline belt.The oil and gas which Sanzhao sag generated also discharge to Fuyu reservoir along the oil source faults in the end of Mingshui group under overpressure,then migration to Chang10 blocks along the matching of Channel sand body and fault concentration belt,forming the oil-gas migration channels,constitute main tectonic background which rich in oil and gas in fuyu reservoir.
