| 摘 要： | “天生盆地必有油，有煤炭的地方一定有煤层气”。煤层气主要以吸附状态储存在煤层的基质孔隙和裂缝孔隙（又称割理）中。全国的煤层气资源量约32万亿m^3，相当于450亿吨标准煤或350亿吨标准油，与陆上常规天然气资源量相当。我省的煤层气资源量约3480亿m^3。开发煤层气应从八个方面去思考和工作，重点是压裂问题、排水采气问题、综合研究问题等。

| Abstract: | Coal bed gas is always associated with coal.Coal bed gas occurs as adsorbed gas in pores and fissures of coal.Coal bed gas resources in our country are about 32000 G m3 which convert into 45 Gt standard coal or 35 Gt standard oil,corresponding to natural gas resources in the China continent.Coal bed gas resources in Sichuan Province are about 348 G m3.This paper deals with eight problems of exploration and exploitation of coal bed gas in Sichuan,especially,problems of pressure burst,drainage and comprehensi... |
