| 摘 要： | 煤层气有利区块优选是煤层气勘探开发的重要研究工作之一。乌鲁木齐-大黄山地区煤层气地质条件复杂，煤层含气量、渗透性等储层条件差异明显。将研究区划分为5个区块，选取构造复杂程度、煤层厚度、含气量、煤层倾角、含气面积、渗透率和含气饱和度等7个指标，运用层次分析法和模糊数学相结合的方法进行区块优选，优选出水磨河-四工河区块、甘河子河-大黄山区块为有利区，四工河-甘河子河区块为较有利区、乌鲁木齐河西区块和乌鲁木齐河-水磨河区块为远景区。

Optimal selection of favorable CBM blocks of Badaowan coal seams in Rumqi-Dahuangshan area |

| Abstract: | Optional selection of favable CBM block is one of the important work in CBM exploration and development. The geologic condition of coalbed methane in Urumqi-Dahuangshan area is very complex. The reservoir conditions such as gas content and permeability of coal seam are obviously different. The study area is divided into 5 blocks. The geological structure complexity, thickness of coal seam, gas content, coal seam dip angle, gas bearing area, permeability and gas saturation are selected by using a combination method of analytic hierarchy process and fuzzy mathematics for block selection. The results show that Shuimo River-Sigong River block and Ganhezi River-Dahuangshan block are favorable areas, Sigong River-Ganhezi River block is the more favorable area, and Urumqi River block on the west and Urumqi River-Shuimo River block are the prospective areas. |
