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 calculation results of CBM in-situ resources and technically recoverable resources can provide the basis for decision-making for CBM development strategies in the country. It can also provide reference for the relevant departments or units that develop CBM, and promote the development of CBM industry in China It is of great significance. Through calculating the amount of CBM resources in the lignite area in our country, we can make up the shortcoming of the long-term shortage of CBM resources in our country and make the CBM resource data more complete in our country. The CBM The amount of in-situ resources is 32.86 × 1012m3, of which the main distribution area of lignite is 1.40 × 1012m3, and the non-lignite area is 31.46 × 1012m3. Based on the established CBM technology recoverable resource assessment method system, and based on the current development technology, the recoverable resource amount of CBM technology in China is calculated, which is 13.90 × 1012m3, accounting for 42% of the in-situ resource.
