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m3,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m3。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。
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 comprehensive study.
