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.
