为了查明青藏高原乌丽冻土区二叠纪煤系烃源岩的生烃潜力，对采集自乌丽水合物试验孔 ZK1井及其周边钻孔的岩心样品和露头样品进行了测试。测试结果显示：上二叠统那益雄组上段烃源岩有机质丰度较低，而下段烃源岩有机质丰度较高；烃源岩有机质类型主要为Ⅲ型；烃源岩热演化程度很高，已达过成熟。考虑到泥质烃源岩成熟度很高以及该区存在变质程度很高的煤层，综合研究认为，该区二叠纪煤系烃源岩生烃潜力总体较好。

In order to find out the hydrocarbon-generating potential of Permian source rocks in Wuli permafrost zone,Qinghai-Tibetan Plateau,the cores from gas-hydrate trial hole (ZK1)and its adjacent drilling holes were analyzed.The results show that the organic matter abundance of upper member source rocks of Nayixiong For-mation in Upper Permian is poor,while the abundance of the lower member is fair to good.The organic type is mainly constituted by Ⅲ kerogen,which is in favor of generating gas.The thermal evolution degree of Permian source rocks is very high,reaching to excessive maturity.Considering that the maturity of mudstone and meta-morphic grade of coal bed are very high in Wuli Permafrost zone,it can be drawn a conclusion that the hydro-carbon-generating potential of Permian source rocks is general good in Wuli permafrost zone,Qinghai-Tibetan Plateau.
