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.
在對國內外煤層氣勘探開髮現狀調研的基礎上,分析瞭不同煤層氣開髮方式的技術特點、技術優勢和存在問題,以及應用現狀和應用效果,併根據不同開髮方式的技術、工藝要求,從地質、儲層,地形和投資等方麵研究瞭主要開髮方式的適應性.基于美國和我國煤層氣地質條件的綜閤對比分析,併針對我國主要煤盆地的地質特徵和地形條件等,提齣瞭相應的煤層氣開髮方式:沁水盆地和鄂爾多斯盆地東緣比較適閤地麵垂直井和定嚮井開髮方式;其他地區因地質條件大都比較複雜等原因,建議首選直井方式進行煤層氣勘探開髮.

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.
