摘　　要：在对国内外煤层气勘探开发现状调研的基础上,分析了不同煤层气开发方式的技术特点、技术优势和存在问题,以及应用现状和应用效果,并根据不同开发方式的技术、工艺要求,从地质、储层、地形和投资等方面研究了主要开发方式的适应性。基于美国和我国煤层气地质条件的综合对比分析,并针对我国主要煤盆地的地质特征和地形条件等,提出了相应的煤层气开发方式:沁水盆地和鄂尔多斯盆地东缘比较适合地面垂直井和定向井开发方式;其他地区因地质条件大都比较复杂等原因,建议首选直井方式进行煤层气勘探开发。Based on the analysis of current status of CBM exploration and development in the world, the effect and adapting conditions, technical characteristics, advantage and existing problems were analyzed for different methods of CBM development. In term of technical and technological requirements of different methods of CBM development, the adaptability of the major CBM development approaches were studied in view of geology, reservoir, topography and investment. On the basis of comprehensive comparison and analysis of CBM geological conditions in China and U.S.A, corresponding CBM development way was proposed. CBM development by surface vertical wells and directional wells is suitable in Qingshui basin and eastern Ordos basin, and exploration and development of CBM by vertical wells is suggested for other areas due to complicated geological conditions.
