| 摘 要： | 多分支水平井是开采煤层气的重要手段.多适用于中、高煤阶煤层,煤层机械强度较高,力学性质稳定;地质条件要求埋深适中,煤层厚度适中,横向连续稳定分布,煤层中夹矸不发育,构造稳定,避开断层和破碎带.煤层气多分支水平井技术最主要的优点表现在,单井产气量高、采收率高、生产周期短、井场占地面积少.不同地质条件需采用不同井型多分支水平井,其经济效益与社会效益不同. |
| 关 键 词： | 煤层 煤层气 多分支水平井 |

| Abstract: | CBM multi-branch horizontal well is applicable to coalbeds of the high rank CBM and mechanical property stabilization.The coalbeds should be appropriate thickness and depth,stable distribution and stable structure.The major advantage of CBM multi-branch horizontal well is high well-gas production rate,high recovery efficiency,short period of production and little floor area.The different geological conditions do correspond with the different type CBM multi-branch horizontal wells.There are different economi... |
