采用直接解吸法、等温吸附法和吸附—解吸法,对研究区上古生界主煤层中煤层气的采收潜势进行分析,得出了一些有意义的结论:在0.7MPa废弃压力水平,推定区中绝大部分矿区的主煤层将可能没有煤层气产出;推断—预测区主煤层的采收潜势以临汾盆地最好,沁源东—安泽和沁水—翼城地区上主煤层也相对较高,而下主煤层普遍较差或极差。
The direct desorption method, isothermal adsorption method and adsorption-desorption method were used to analyze the recovery potential of coalbed gas in the main Paleozoic coal seam in the study area. Some meaningful conclusions were drawn: At the abandoned pressure of 0.7MPa, The main coal seams in most of the mines in the presumption area will probably not have any CBM output. Inferred-Predicting the recovery potential of the main coal seams is the best in Linfen Basin, the Qinyuan-Anze and Qinshui-Yicheng areas The coal seam is also relatively high, while the lower main seam is generally poor or poor.
