| 摘 要： | 文章分析了影响我国煤层气采收率的主要因素，认为低渗透、低储层压力和低饱和度等煤层气地质特征以及常规开发技术是影响我国煤层气采收率的瓶颈。指出改造“虚拟产层”，采煤、采气一体化开发以及应用多分支水平井钻井技术，是提高我国煤层气采收率和实现我国煤层气地面开发商业化切实有效的途径。 |
| 关 键 词： | 煤层气 采收率 储层激励 多分支水平井 |

| Abstract: | Key factors affecting CBM recovery in China are analyzed in the paper. The`bottle-neck' issues regarding low CBM recovery are considered to be CBM geological features such as poor permeability, low reservoir pressure, low saturation and regular development technologies. Based on analysis on major techniques and mechanism of output growth aiming at increasing CBM recovery, improvement of`dummy layer', integrated development of gas & coal and employment of multi-branch horizontal well technology are effective ways to increase CBM recovery and achieve commercial surface development of CBM in China. |
| Keywords: | Coalbed methane recovery rate reservoir excitement multi-branch horizontal well |
