摘　　要：天山含煤盆地侏罗系下统八道湾组和中统西山窑组,含煤2～48层,累计厚度15～110m,一般厚度30～60m,累计含煤面积24260km2。埋深2000m以浅区域煤层气资源总量达16261.50×108m3,有着广泛的煤层气勘探开发前景。综合考虑含煤区煤层气地质背景,煤层气赋存地质条件及各项参数的变化特征,对八个含煤区进行了煤层气资源勘探前景分析,共划分出前景有利区和较有利区两种类型区。前景有利区包括伊宁、焉耆含煤区;较有利区包括尼勒克、昭苏、巩留新源、可拉克含煤区,尤尔都斯含煤区,库米什含煤区。The Badaowan Formation of Lower Series and Xishanyao Formation of the Middle Series of Jurassic System of the Tianshan Coal-Bearing Basin contain 2 - 48 coal-bearing seams. The cumulative thickness is 15 110m. The thickness of seams generally varies from 30 to 60m. The coal-bearing area is 24260km^2. The total CBM resource to a depth of 2000m is 16261.50× 10^8m^3. It has a broad prospect for exploration and development of coalbed methane. Based on overall consideration of the geological settings of CBM in the coal-bearing zone, the geological occurrence conditions of CBM and variations of all the parameters, the coal-bearing areas fall into two categories： namely, the favorable area, including Yining and Yanqi coal-bearing areas, and the fairly favorable area, including Nileke, Zhaosu, Gongliuxinyuan, Kelake coal-bearing areas, Youerdus coal - bearing area and Kumish coal-bearing area.
