摘　　要：主要论述以上古生界为烃源岩的典型煤型气藏的地球化学特征、形成时的构造环境与气藏类型及找气前景。华北聚煤区为最有利地区，并总结出煤型气藏形成的２种构造环境和４种成藏类型：裂谷活动构造环境中的古潜山自生自储型（苏桥型）、古生新储型（文留型）和克拉通稳定构造环境中的复合型（鄂尔多斯型）及自生自储型。前述４种气藏类型应为今后该区煤型气勘探的主要类型。此外，还对上述两种构造环境中的煤层气问题进行了扼要讨论。The paper mainly discusses the geochemical characteristics and types of the typical coal type gas pools of the Upper Paleozoic,the tectonic environments and exploration prospects in China.North China coal accumulating area is the most favourable area. Two kinds of tectonic environments and four types of coal type gas pools have been concluded,self generated self reservoired type of ancient burial hill(Suqiao type) and paleogenerated neoreservoired type (Wenliu type) in tectonically active rift region,combination type(Ordos type) and self generated self reservoired type in tectonically stable region of craton. The four types above should be the major types for exploring coal type gas in the areas.The coalbed gases are also briefly discussed in the two kinds of tectonic environments.
