According to the geochemical characteristics of source rocks and crude oils, the oil-source correlation of Putaohua and Fuyang oil layer in South Songzhan area, Songliao Basin was analyzed. The results show that the oils of Putaohua and Fuyang oil layer in South Songzhan area and in Sanzhao depression have the same source and the oils are all mainly derived from the hydrocarbon source rock of the first member of Qingshankou Formation, second from the second and third member of Qingshankou Formation. Inside the oil source area of South Songzhan, the oil of Putaohua layer is mainly from the oil generated from the first member of Qingshankou formation and the oil migrates along the effective faults due to the buoyancy of water. Under the effect of paleo-overpressure, the oil of Putaohua layer together with the oil expelled from the Qingshankou formation can migrate downward into Fuyang payzone along the T2 faults. The oil from Sanzhao depression, the large hydrocarbon-generating depression of the basin, can be effectively transported to South Songzhan area through the path of faults and sandbody.
