【Abstract】 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.更多还原
