摘要： 对羌塘盆地南部下侏罗统曲色组页岩出露地区进行了野外调查、样品采集及测试分析。研究认为，羌塘盆地下侏罗统曲色组黑色页岩厚度大（600~1 200 m），有机碳含量高（0.40%~9.65%），热演化程度高，页岩镜质体反射率为1.78%~2.15%，具有形成页岩气藏资源的良好潜力。依据研究区页岩厚度、有机碳含量和成熟度特征以及页岩矿物成分、孔裂隙和吸附性研究等气源岩和储集层方面综合分析，优选出毕洛错—木苟日王和其香错—噶尔敖包2个页岩气勘探远景区。

Abstract: The investigation, sample collection and laboratory analyses of Quse shale outcrops of the Lower Jurassic in southern Qiangtang basin showed that the Quse shales are characterized by big thickness (600~1200 m), high organic carbon content (0.40%~9.65%) and high degree of thermal evolution (Ro averages 1.78%~2.15%), having good potentials for forming shale gas resources. According to these characteristics and the shale mineral composition, porosity and adsorbability, two prospective areas for shale gas exploration are selected, one is Biluocuo?Mugouriwang area, the other is Qixiangcuo-Gaeraobao area
