摘　　要：以盆地内烃源岩的演化历史和构造发展史为基础,确定油气生成时间及圈闭构造形成时间,结合已钻探构造的含油气特征,分析总结出区内的油气成藏过程。认为伊朗三区南部逆冲群后缘带内的圈闭以聚集油为主,逆冲群中带的圈闭以聚集气为主,而逆冲群峰带内的圈闭对油气保存不利,因此勘探效果和前景也不理想。这为该区块今后找油气指明了有利区分布范围,同时也提出了前陆盆地油气的分布模式。This paper presents period of hydrocarbon generation and trap structure formation in piedmont of Zagros foreland basin of Iran in view of the evolution history of source rocks and tectonic development history in this basin,and discusses its overall process of hydrocarbon accumulation from hydrocarbon-bearing characteristics in drilled structures.It is suggested that traps in the trailing edge of thrust group in southern Block-3 of Iran are dominated by oil accumulation,those in the middle of thrust group dominated by gas accumulation,while those in the peak of it are unfavorable for conservation and unsatisfactory in terms of exploration result and prospect.These recognitions can help to delineate the favorable places for oil-gas prospecting,and provide the significant pattern of hydrocarbon distribution in foreland basins.
