摘　　要：总结了前陆盆地研究的历史和现状,对前陆盆地的定义、构造-沉积样式、类型和油气系统进行了综述,同时对中国中西部再生前陆盆地的特征、归属和含油气性进行初步探讨。在此基础上,得到了以下认识:就分类而言,陆内再生前陆盆地是与弧后前陆盆地和板缘前陆盆地并列的一种前陆盆地,大致又可分为3种类型:弧后前陆盆地、板缘前陆盆地和陆内再生前陆盆地;由于每一种类型前陆盆地在大地构造背景和演化特点等方面存在差异。This paper reviews the previous and current research on foreland basins, including the concept, modes of tectonics-sedimentation, types, characteristics, and hydrocarbon bearing features. At the same time, the features and hydrocarbon potential of the rejuvenated foreland basins around intracontinental orogens in Mid-West China are discussed. Conclusions are as follows: ① The rejuvenated foreland basins, juxtaposing with peripheral foreland basin and retro-arc foreland basins, should be considered as a main type of foreland basins; ② The foreland basins, on the basis of their geodynamic environments, can be subdivided into three fundamental types: the peripheral foreland basins, retro-arc foreland basins and rejuvenated foreland basins. The former two types are the representative foreland basins, and the latter one is a rather unique type around introcontinental orogens in the Mid-West of China. ③ Due to different regional background and evolutional processes of three types of foreland basins, individual styles of oil and gas system are developed in these foreland basins.
