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。Abstract: The paper mainly discusses the geochemical characteristics and types of the typical coal-typeg as pools of the Upper Paleo zoic, 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.
