摘　　要：综合分析昭苏盆地地质调查、钻孔及测井资料,采用沉积学及沉积相分析方法,对其沉积环境及聚煤规律进行研究。结果表明,昭苏盆地含煤地层具典型泥-砂(砾)-泥(煤)结构,为近物源山间内陆湖相沉积环境。沉积体系主要发育冲积扇、扇三角洲、辫状河和三角洲沉积。煤层主要发育于下—中侏罗统八道湾组和西山窑组中,煤层层数、厚度和垂向分布具一定差异,形成受盆地构造和沉积演化及物源碎屑供给控制。Based on the theories of the sedimentology and sedimentary facies,this article comprehensive analysis the information from the geology surveys,drilling cores and well logs of Zhaosu basin,Xinjiang.The sedimentary environment and coal accumulation is studied.The rusults show that the coal-bearing formation has a typical structure with mud and sand（gravel）- mud（coal） in the mountains nearly source inland lake facies sedimentary environment.The alluvial fan,fan delta,braided river and delta sedimentary system are developed.The Coal- bearing formations are mainil composed of Badaowa formation and Xinshanyao formation of Middle-Lower Jurassic.The number of layers,thickness and the vertical distribution are difference.The formation of coal is controled by the basin tectonic and sedimentary evolution and source clastic supply.
