Migration Pathways of Fuyu Oil Layer in Chang 10 Block in Songliao Basin and Its Control on Oil Accumulation

FU Guang LIU Mei-wei ( Daqing Petroleum Institute,Daqing,Heilongjiang 163318)  
Through oil reservoir anatomization and analyzing its spatial-temporal relationship with reservoir forming condition,migration pathways and the control on oil accumulation and distribution were studied on the basis of summarizing oil migration mechanism and mode in Fuyu oil layer in Chang 10 block. It was considered that oil migration pathways of Fuyu oil layer in Chang 10 block were as follows in main. ①T2 source faults are transporting pathways through which oil that generated by K1qn1 source rock migrated downward into underlying F,Y oil layers in Sanzhao depression. ②Faults combining with sand bodies are transporting pathways of oil in Fuyu oil layer in Sanzhao depres-sion migrating laterally to Chang 10 block. The controlling roles of oil migration pathways of Fuyu oil layer in Chang 10 block to oil accumulation and distribution are mainly manifested as:①Development degree of T2 source faults controls oil supply amount of Fuyu oil layer in Chang 10 block. ②Fault concentrated belts are main oil accumulation areas of Fuyu oil layer in Chang 10 block,and high fault block connected by transporting pathways that formed by faults combing with sand bodies are main oil accumulation positions.
