摘　　要：根据油气单一运移通道特征,建立惠民凹陷南部地区油气运移通道组合类型,并系统总结其成藏作用。结果表明:惠民凹陷南部地区主要发育连通砂体、断层及不整合3种油气运移通道,形成了砂体-断层-砂体、砂体-断层-不整合和砂体-不整合3种组合类型;这些组合类型不仅控制了油气运移模式,发育反'Z'字型输导运移模式、阶梯状输导运移模式等,而且控制了油气空间分布特征;砂体-断层-不整合型和砂体-不整合型决定曲堤地区油气具有'多层系分布、油气藏类型多样、运移距离远'的特征;单一的砂体-断层-砂体组合类型决定钱官屯地区油气具有'单层系分布、油气藏类型单一、运移距离近'的特点。The composite models of migration pathways in the south of Huimin depression were established based on the characteristics of single oil and gas migration pathways, and their contributions to hydrocarbon accumulation were evaluated. The results show that the connective sandbody, fault and unconformity are mainly developed in the south of Huimin depression. They can be combined to form three composite models： sand-fauh-sand, sand-fault-unconformity and sand-unconformity. These composite models dominate the migration patterns of hydrocarbons by forming anti-Z type and ladder type migrational patterns. In addition, they also control the hydrocarbon spatial distribution. Composite models in Qu-di include sand-faultunconformity and sand-unconformity, which results in the diversity of oil-bearing series and reservoir types as well as the character of hydrocarbon＇s distant migration. The sole model of sand-fauh-sand in Qianguan-tun determines the single of oilbearing series and reservoir types as well as the character of hydrocarbon＇s short migration.
