摘　　要：煤系中广泛存有与煤炭共生的多种能源矿产,因此对含煤盆地进行综合地质研究与勘探开发具有现实必要性。我国聚煤时期跨度长、煤系地层分布广、聚煤盆地面积大,含煤岩系中的有机质含量高、岩石旋回性强、以Ⅲ型干酪根为主、储层陆源物质丰富、多期构造热演化等特点奠定了煤系非常规天然气具有发育良好的物质基础。针对煤层气、页岩气、致密砂岩气、天然气水合物等不同煤系非常规天然气的基础特征与研究现状,提出了煤系非常规天然气共生赋存模式及其研究方向,为我国开展煤系非常规天然气地质与开发工作提供基础理论指导。There is practical necessity of comprehensive geological research and exploration and development of coal-bearing basin because of extensive developed coal and symbiosis multiple energy resources in coal measure.There is a long coal accumulating time, widely distrib- uted coal measure strata, and large coal accumulating area in China. Characteristics of coal measure strata like high organic matter content, strong cyclicity of the sediments, main kerogen of IU type, rich terrigenous materials, and multi-period teclonothermal evolution set a good foundation for development of unconventional gas in coal measure strata.Aiming at the basic characteristics and research status of uncon- ventional gas in coal measure strata like coalbed methane, shale gas, tight sandstone gas and natural gas hydrates, the mode of symbiotic oc- currence of unconventional gas was proposed, and several scientific issues and development trend for comprehensive study were discussed. The research can provide a theoretical basis and guide direction for geology and development of unconventional gas in China.
