摘　　要：对平南油田断裂带内包裹体及储层流体包裹体利用显微镜进行了岩相学研究,利用Linkam THMS600冷热台及JY LabRaman-010进行了测温分析,认为:平南断层是一条力学性质复杂的断层,经历过正、负反转过程;平南地区奥陶系和寒武系储层的油气成藏时间主要在明化镇期,且寒武系充注时间相对集中;靠近平南断层的地方油气充注时间要早于远离断层的地方,并且油气充注时期与断层的活动时期相吻合,说明了断层在油气聚集成藏中起到了运移通道的作用。We studied the petrography of inclusions in fault zone and liquid inclusions of reservoirs in Pingnan oilfield by using microscope and conducted the temperature analysis by using Linkam THMS600 and JY LabRaman-010. Then,we concluded that the Pingnan fault was one with very complex mechanical properties, which experienced the process from normal to reverse. The oil-gas reservoir-forming times in the Ordovician and Cambrian systems in Pingnan area were mainly at the period of Minghua town, and the oil reservoir-forming at the time of Cambrian system was relatively concentrated. The oil reservoir-forming time near the Pingnan fault was earlier than that far away from the fault. The oil-gas infilling time was coincident with the fault motion,which showed that the fault was the migration pathway during the oil-gas reservoir formation.
