松辽盆地北部西斜坡主要有背斜、构造-岩性、岩性上倾尖灭、透镜体、断层遮挡和地层不整合6种类型油气藏，主要目的层为高台子油层和萨尔图油层。在研究油气藏类型及特征的基础上，通过油气分布规律和成藏期次的研究，总结出松辽盆地北部西斜坡油气运聚成藏模式主要有6种，即地层不整合圈闭油气运聚成藏模式、砂岩上倾尖灭圈闭油气运聚成藏模式、构造及构造-岩性圈闭油气运聚成藏模式、断层一岩性圈闭油气运聚成藏模式、断层遮挡圈闭油气运聚成藏模式、砂岩透镜体圈闭油气运聚成藏模式，并确定了油气成藏与分布的主控因素。

There are 6 kinds of oil and gas reservoir in west slope of the north of Songliao basin： anticline reservoir, structural-lithology reservoir, lithology updip pinchout reservoir, lens reservoir, fault screened hydrocarbon reservoir and stratigraphic unconformity reservoir. The main target stratum are Gaotaizi and Saertu. On the basis of studying the oil and gas reservoir type and characteristic, through analyzing the distributed law and pool forming period, summarizing 6 kinds of pool-forming pattern of hydrocarbon migration and accumulation： stratigraphic unconformity trap pool-forming pattern; sand updip pinchout trap pool-forming pattern; structure and structural-lithology trap pool-forming pattern; fauh-lithology trap pool-forming pattern; fault screened trap pool-forming pattern and sand lens trap pool-forming pattern. And confirming main control factors of pool-forming and distribution.
