    • 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.
