| 摘 要： | 采用地质类比、等温吸附曲线及储层数值模拟 3种方法对山西沁水煤层气田主力气层———二叠系山西组 3# 煤层、石炭系太原组 15 # 煤层的煤层气采收率进行了预测 ,结果 3# 煤层的煤层气采收率为 6 2 % ,15 # 煤层的采收率为 5 5 % ,总平均采收率为 5 9%。分析对比了这 3种方法的运用条件及优缺点 ,指出煤层气采收率的预测必须采用多种方法 ,并结合具体的煤层气地质特点进行综合分析 ,才能得出合理的结论。 |
| 关 键 词： | 煤层气 采收率 等温吸附曲线 数值模拟 沁水盆地 |

| Abstract: | By means of geologic analogy ,adsorption isotherm curves and numerical simulation, the recovery efficiency of C-P in Qinshui coalbed gas field have been worked out. It has two principal coal seams: Permian coal (No 3) seam's coalbed methane recovery efficiency is 62%; Carboniferous coal (No 15) seam's recovery efficiency is 55%. The average recovery efficiency of this two principal coal seams is 59%.These three methods have different scopes of application and different advantages and disadvantages. In order to get a reasonable recovery efficiency,all these three methods should be used and analyzed synthetically. |
| Keywords: | coalbed methane recovery efficiency adsorption isotherm curve numerical simulation the Qinshui Basin |
