| 摘 要： | 基于甲烷在不同矿化度水中和煤层水中溶解度的物理模拟,计算了褐煤层水溶气的含量。基于煤基块、气、水三相介质煤岩体三轴压缩实验,结合理想气体状态方程和马略特定律,推算了褐煤层游离气的含量。基于平衡水等温吸附实验,估算了褐煤层中的吸附气含量。以内蒙古海拉尔盆地为例,对褐煤层的含气量进行了预测

| Abstract: | Based on physical simulates of methane-solubility in water of different minefields and coalbed water, gas-dissolving in the lignite re servoir of Hailaer basin in Neimenggu municipality were calculated. Based on triaxiality compress experiments of three-phase medium coal rocks, i.e. coal matrix, gas and water, integrated into state equation of ideal gas and Malueta law, free gas in the lignite reservoir were calculated. Based on isothermal methane-adsorbing experiments under equilibrium moisture, gas-adsorbing in the lignite reservoir were estimated. At last, taking Hailaer basin as an example, total gas content in the lignite reservoir were predicted. |
