煤层气(煤矿瓦斯)是优质清洁能源,全球埋深浅于2000m的煤层气资源约为240万亿m3,其中,我国的资源量约36.81万亿m3,居世界第三位。煤层气是常规天然气探明储量的2倍多,世界主要产煤国都十分重视开发煤层气。我国“十一五”规划中将煤层气列为重要的发展产业,并制定了一系列政策措施,强力推进煤层气的开发利用。 Coalbed methane (CMM) is a high-quality and clean energy source. The total CBM resources with a depth of less than 2000m are about 240 trillion m3 globally, of which 36.81 trillion m3 is the largest in China, ranking the third in the world. CBM is more than twice as much as the proven reserves of conventional natural gas. The world’s major coal producing countries attach great importance to the development of CBM. China’s “Eleventh Five-Year Plan” listed CBM as an important development industry and formulated a series of policies and measures to vigorously promote the development and utilization of CBM.
