摘要
本文研究柴达木盆地东部地区第四系生物气的组分及碳、氢同位素组成，探讨了气体中不同组分的成因及来源。利用有机酸的研究结果，并结合其它有机地球化学数据，对本区生物气源岩进行了评价，认为柴达木盆地东部第四系生物成因的天然气源岩主要发育在Ｋ１０标准层以上。
In this paper, the components, carbon and hydrogen isotopic composition of biogenic gas occured in the Quaternary in eastern Qaidam basin were analysed, and the origins of the various components in gas were discussed as well. Simultaneously, based on the study of the organic acids and othe organic geochemical data. gas source rocks in the region was evaluated. In authors opinion, the effeCtive source rocks for the biogcnic gas of tile Qua ternary in eastern Qaidam basin should be occured shallower than the K10 standard formation.
