文章基于大量煤田地质勘探和煤层气试井成果,结合实验室测试资料,计算煤层气的解吸率、理论采收率和瓦斯抽采率,确定河北省煤层气可采系数,为本省煤层气可采资源量的计算提供了依据。
Based on a large number of results that coal geological exploration and coal - bed methane test of well, combined with laboratory test data, calculated desorption rate,theoretical recovery rate and gas recovery of coalbed methane to determine recoverable coalbed methane coefficient of Hebei Province, to provide basis of coalbed methane recoverable resources calculation of the province .
