摘　　要：松辽盆地北部扶余油层油主要来自上覆青山口组一段源岩,是源岩生成的油经过油源断裂向扶余油层倒灌运移后,再在浮力作用下沿连通的断砂组合体侧向运移的结果.综合油气输导体系和烃源岩两个成藏要素,分析了油气分布规律.结果表明：扶余油层已发现油田主要发育裂缝—断层—砂体复合型输导体系;油气主要沿断裂带富集,但富集程度存在差异;在有效烃源岩分布范围内,被断层和裂缝沟通的砂体更有利于成藏。The oil in Fuyu reservoirs of North Songliao Basin comes from the overlying K2qn1 source rocks,the generated hydrocarbon has been pouring into the underlying Fuyu oil layers along the source faults and then laterally migrating along the open fault-sandbody connection under the buoyancy.Through the integrated analysis between the two accumulating factors i.e.oil and gas transporting systems and hydrocarbon source rocks has shown the laws of the petroleum distribution.The results indicate that the main well-developed fracture-fault-sandbody complex transporting system in the oilfield is found in Fuyu oil layers; the hydrocarbon is principally enriched along the fracture belts,but the accumulated degree is different; within the scope of the effective hydrocarbon source rock distribution,the hydrocarbon is easily prone to accumulate in the sandbodies penetrated and communicated by the faults and fractures.
