Analysis method and geological significance of C5-C7 light hydrocarbons in natural gas hydrate in permafrost, Qilian Mountain

  • 摘要: 通过自行研发的一套真空密闭加热脱附以及冷柱头零压力进样装置,对采集到的顶空气样进行轻烃在线分析,实现了天然气水合物轻烃C5-C7化合物的有效检测。根据Kováts保留指数等前人研究成果,对祁连山木里煤田聚乎更矿区天然气水合物轻烃中C5-C7共27个单体化合物进行了定性分析,对该区天然气水合物的轻烃地球化学进行研究。利用甲基环己烷指数对该区天然气水合物成因类型进行划分,揭示木里冻土区天然气水合物气体有2种成因3种类型,其中以混合型为主,并伴有少部分的油型气和煤型气。
