摘　　要：吐哈盆地是我国西北典型的侏罗系含煤盆地,十三间房邻区小草湖次凹开采出大量的煤成气,为了打开十三间房探区煤成气的勘探局面,在综合利用录井、岩心、测井及地震资料的基础上,结合区域滑脱断层的追踪,对该区煤层进行了识别与追踪,系统分析了该区煤层的分布范围及厚度情况。结果认为:十三间房探区煤系烃源岩主要为水西沟群(八道湾组和西山窑组)煤系烃源岩,煤层主要分布于区块北部山前带,厚度呈北厚南薄,向了墩隆起尖灭,西山窑组煤层较八道湾组分布广厚度大。Turpan-Hami basin was deemed to be a typical coal measure basin.a lot of coal derived gas was found in Shisanjianfang neighborhood Xiaocaohu depression,To open Shisanjianfang's coal derived gas exploration situation,based on utilization of logging,core logging and seismic data,combined with the regional detachment fault trace,the coal of the area is identificated and tracked,and the coal's distribution range and thickness case was Systematiciy analysised in the area.The results show:The coal source rocks of Shisanjianfang area are mainly Shuixigou Group(Badaowan and Xishanyao)coal source rocks.The Coal is mainly distributed in the northern piedmont zone,which the thickness was thick in north and thin in south,and pinch out to the pier uplift.Xishanyao grounp seam widerand larger than Badaowan grounp.
