摘　　要：对青海木里地区天然气水合物的分布赋存与地层、岩性进行研究。研究结果表明:研究区钻探孔揭露的地层主要为第四系、中侏罗统木里组及江仓组,其次还有上三叠统尕勒得寺组;矿物成分以石英和黏土矿物为主;通过化学元素及其相关元素比值的研究,可得出江仓组下段及木里组上段距离物源区相对较远,而江仓组上段则距离物源区相对较近。Analyzes the distribution of natural gas hydrate, strata and lithology. The results show that the strata revealed by the drilling wells in the study area conclude Quaternary,the middle Jurassic Muli formation and Jiangcang formation, besides that,it concludes the Triassic Galede temple formation.Mineral components is mainly quartz and clay minerals. By studying the chemical elements and element ratio, the lower Jiangcang formation and the upper Muli formation is far from the source area, but the upper Jiangcang formation is near.
