摘　　要：针对三塘湖盆地沉积充填和构造演化特征,从油气成藏角度综合运用输导体系研究方法,分析了盆地输导体系的构成,重点剖析了输导体系对侏罗系油藏形成的控制作用。研究表明,该盆地侏罗系油藏输导体系主要为断裂、不整合面和连通砂体,断裂控制了油藏的纵向分布,不整合面和砂体的输导性能控制了油藏的平面展布。不同输导要素相互组合形成了断层—不整合—砂体型和断层—砂体型复合输导体系,它们控制了逆冲褶皱带、斜坡带两种成藏模式。进一步揭示了油气成藏规律,为油气勘探提供了理论依据。Based on the study of structural evolution and sedimentary filling of Santanghu Basin,in terms of hydrocarbon accumulation,this article analyses the hydrocarbon passage system and their controlling on hydrocarbon migration by use of the study method of passage system comprehensively.The results show that unconformity,fault and sand body are identified as three important pathway types in this area.Faults control the longitudinal distribution of Jurassic reservoir,the migrating capability of unconformity and sand body controls the planar distribution of Jurassic reservoir.The compound passage system,including fault-unconformity-sand body type and fault-sand body type that control two models of hydrocarbon accumulation,is formed by the combination of different elements.And the rule of oil and gas accumulation is further studied,which provides theoretical basis for oil and gas exploration.
