摘　　要：回顾了我国煤层气资源勘探开发试验工作进程 ;根据 2 0 0多煤层次的注入 /压降试井数据以及多年来的煤田地质勘探资料 ,简要总结了我国煤层气储层基本特点 ;对今后我国煤层气资源勘探开发策略和思路提出了建议 ,认为我国煤层气开发 ,应针对各地的资源特点 ,因地制宜地选择合适的开发方式 ,不仅要在诸如河东、沁水等重点煤田继续进行常规垂直压裂井开发试验 ,同时要大力提倡开展煤矿采动区地面井开发煤层气的试验工作 .此外 。In this paper, the course of the coalbed methane resource exploration and development in China has been outlined. Based on the analysis and test data available from over 200 CBM wells drilled in recent ten years, as well as the geological information from the coal exploration performed in last thirty years, the basic characteristics of CBM reservoirs in China have been summarized. Furthermore, the suggestions on the further exploration and development strategy of CBM resource in China in near future have been made. It is suggested that the suitable CBM development ways and technologies should be selected in accordance with the local CBM resource conditions in the different coalfields or coal-bearing areas in China. In China in the near future, not only CBM development by conventional vertical fractured wells will be continuously carried out in the key coalfields such as Hedong and Qinshui coalfields, but also the CBM development tests by the gob surface wells would be initiated and encouraged energetically in coal mines. In addition, the attention should be brought to the development of CBM resource in Jurassic coalfields with low-rank coal in Northwest China.
