摘要
本文根据组分及甲烷同系物的碳氢同位素确定柴达木盆地东部第四系天然气为生物气类型；根据地化分析和生物模拟，论述了第四纪沉积有机质的地球化学特征，对第四系生物气源岩进行了评价，并对生物气前景提出了预测。
The Quaternary natural gas in the east of Qaidam basin is determined to be biogenic gas through a studying of gas composition, carbon and hydrogen isotopes in methane. Based on geochemical analyses and biological simulation, this paper discusses the geochemical properties of organic matters in Quaternary sediments, and evaluates the biogas source rocks and gives a prediction for biogas prospects.
