摘　　要：对我国不同地区、不同时代、不同煤盆地、不同变质程度的煤的等温吸附性能进行了实验。实验结果表明:煤的吸附性能受到煤的变质程度、储层温度、储层压力以及煤中水分类型及水分含量多方面因素的影响。通过对这些影响因素的分析,力求对我国煤层气资源的选区、勘探、开发提供依据。Using the result of adsorbing experimentation at same temperature of various metamorphose coal collected in different coal basin of China, the authors realizes that the adsorbing capability of coal come under many affecting factors, including the metamorphose degree of coal, the temperature of CBM stored layer, the pressure of CBM stored layer, the moisture type and content, in order to offer direction to appraise, explore and develop the CBM of China.
