中文摘要：

根据烃源岩、原油地球化学特征,对宋站南地区葡萄花、扶杨油层进行油源对比分析。结果表明：宋站南区葡萄花油层、扶杨油层的油同源,并与三肇凹陷的葡萄花油层、扶杨油层的油同源,均主要来自于青一段烃源岩,其次来自于青二、三段烃源岩;宋站南油源区内葡萄花油层的油主要由青一段烃源岩生成的油在浮力作用下沿有效的断裂通道运移为主,葡萄花油层的油和青山口组烃源岩大量排出的油在古超压作用下通过T2断裂可以向扶杨油层＂倒灌＂运移;大型生烃凹陷三肇凹陷的油在有效的断裂、砂体等通道的沟通下,能够输导到宋站南地区。

英文摘要：

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.
