摘　　要：通过对中国西部低阶煤储层煤层气资源分布及赋存特征的研究,认为西北地区煤储层含气量较低,但因煤层巨厚特征导致它含有巨大的煤层气资源量,占中国低阶煤层气总资源量的53.1%。另外,煤层气资源分布极不均匀,主要分布在新疆地区的准噶尔盆地和吐哈盆地。当前的开发实践显示,西北地区具有巨大的开发前景,但勘探开发主要集中在准噶尔盆地和吐哈盆地局部地区,仍需要加大勘探开发力度,加强煤层气战略选区评价。Through the research on the distribution and occurrence characteristics of coalbed methane resources in low rank coal reservoirs in western China,it is believed that the gas content of coal reservoirs in northwest China is low,but because of the huge thickness of coal seams,it contains huge coalbed methane resources,accounting for 53.1%of the total low rank coalbed methane resources in China.However,the distribution of coalbed methane resources is extremely uneven,mainly distributed in Junggar Basin and Tuha Basin in Xinjiang.The current development practice shows that the northwest region has a huge development prospect,but the exploration and development are mainly concentrated in the local areas of the Zhungar Basin and Tuha Basin,so it is still necessary to increase the exploration and development efforts and strengthen the evaluation of the strategic selection of coalbed methane areas.
