摘　　要：平顶山煤层气区块位于河南省平顶山市,地面钻探和煤矿巷道瓦斯抽采证实其具有很好的煤层气勘探潜力,但煤层气富集主控因素尚不明确。本文根据该区块的勘探开发资料,综合分析了研究区煤层气基本地质条件,认为该区煤层气富集主要受构造条件、沉积环境、水文地质条件控制,剖析了其控制机理,优选了有利目标区。本次研究为降低该区煤层气开发风险和成本提供了保障,为下一步勘探开发工作提供了依据。Pingdingshan coalbed methane block locates at Pingdingshan city in Henan province. Ground drilling exploration and gas drainage at coal mine roadway have proven that it is of excellent coalbed methane exploration potential, but main controlling factors for coalbed methane enrichment remain unidentified. The authors discuss basic geological conditions of coalbed methane within the researched area based on exploration and development data of this block, believe that the coalbed methane enrichment within the block is mainly restricted by structural environment, sedimentary environment and hydrogeological condition, analyze its control mechanism and preferentially select the favorable target areas. The study guarantees to reduce coalbed methane development risks and costs within the block, and provides basis for further exploration and development.
