煤层气开发包括多个阶段,最终是地质和工程之间的匹配。地质是基础,指导工程开发,同时,需利用工程开发反馈不断修正地质认识。基于我国煤层气开发地质条件,总结分析了煤层气开发技术及其地质适应性,并在探讨国内外煤层气开发技术发展趋势的基础上,结合我国煤层气开发现状,阐述了我国典型地区的煤层气开发技术趋势。研究认为,我国煤层气勘探开发将逐渐向黔西滇东、准噶尔盆地南部和豫西等地延伸;煤层气开发对象将由浅层、中高煤级、单一煤层和煤层气单采逐渐向深部、低煤级、多煤层和煤系气发展,相应的开发技术也逐渐向自动化和多样性方向发展。

The coalbed methane development would include several stages and the final would be the match between the geology and the engineering. The geolog y would be the base to guide the engineering development. Meanwhile the feedback of the engineering development would be applied to continuously revise the geologi cal cognition. Based on the geological condition of the coalbed methane development in China, the paper summarized and analyzed the coalbed methane developmentt echnology and the geological suitability. Based on the discussion on the development tendency of the coalbed methane development technology at home and abroad, in combination with the coalbed methane development status in China, the paper stated the tendency of the coalbed methane development technology in China typical are as. The study showed that the coalbed methane survey and development in China would steadily be expanded to the West Guizhou and the East Yunnan, the south part of Junggar Basin, the West Henan and other places. The objects of the coalbed methane development would be developed from the shallow seam, medium and high ran k coal, single seam and coalbed methane mining only to the deep depth, low rank coal multi seams and coal measures gas and the relevant development technology als o would be steadily developed to the full mechanization and multi directions.
