提要：通过对吐哈盆地页岩的分布、厚度、有机质丰度及有机质成熟度进行分析，结合页岩矿物成分进行裂缝发育及气体吸附能力的评价，并综合盖层分布、储层物性特征以及显著的气测数据对页岩气成藏条件进行研究发现：吐哈盆地中、下二叠统桃东沟群与中、上三叠统小泉沟群的页岩厚度大、脆性矿物种类多且含量高，有机质丰度大，盖层条件好，是比较有利的页岩气勘探层位。进一步预测台南凹陷、台北凹陷南缘、托克逊回陷的西部及北部地区是桃
东沟群页岩气勘探有利区，三堡凹陷是小泉沟群页岩气勘探的有利区域。关键调：吐哈盆地；页岩气；富集条件；矿物特征；地化特征；有利区预测

Abstract: Based on analyzing the distribution, thickness, total organic carbon content, degree of organic metamorphism of the shale of Turpan Hami Basin, evaluating the fomation of fractures and the capability of adsorbing gas in consideration of the mineral composition, and studying the conditions of shale gas accumulation by analyzing the distribution of cap rocks, the physical property of reservoir, and the data of gas surveying, the authors consider that the shales in MiddleLower Permian Taodonggou Group and the MiddleUpper Triassic Xiaoquangou Group have the bigger thickness, higher brittle mineral content, higher degree of thermal evolution, and preferable situation of cap rock, thus probably being the potential horizons of shale gas exploration, The Taodonggou Group of Tainan depression, the north of Taiben depression and the northwest of Tuokexun depression and the Xiaoquangou Group shale of Sanbao depression are favorable areas for gas exploration.
