摘　　要：煤层气原地资源量和技术可采资源量的计算结果,可为国家制定煤层气开发战略提供决策依据,也可为煤层气开发的相关部门或单位提供参考依据,对推动我国煤层气产业发展具有重要意义。通过对我国褐煤分布区的煤层气资源量的计算,弥补了我国长期缺少褐煤煤层气资源量的缺陷,使我国煤层气资源量数据更加完整,我国陆上煤层埋深2 000 m以浅的煤层气原地资源量为32.86×1012m3,其中,褐煤主要分布区为1.40×1012m3,非褐煤地区为31.46×1012m3。利用已建立的煤层气技术可采资源量评价方法体系,并基于目前的开发技术,对我国煤层气技术可采资源量进行计算,结果为13.90×1012m3,占原地资源量的42%。The calculated results of coalbed gas resources in place and technically recoverable resources are important for govemment to design coalbed gas development strategy and can service as consideration basis for gas development related departments and institutions. Therefore the data of gas in place resources and technically recoverable resources are of great significance for China combed gas development. In this paper the lignite resources are calculated, supplementing this item of resources, which is lack for a long time in coalbed gas resources calculation. In China the total continental coalbed gas in place （ Gip ） at depth shallower than 2 000 m is as much as 32.86 × 10^12 m^3, from that in the area where lignite widely distributed the resources are about 1.40×10^12 m^3 , but in the area where without lignite the resources are as much as 31.46× 10^12 m^3 . Based on established assessment system of coalbed gas technically recoverable resources and considering the current technical measures for gas development the China recoverable coalbed gas resources are as much as 13.90× 10^12 m^3 , being 42% of total coalbed gas resources in place.
