摘　　要：柴达木盆地是中国第四大气区,按照碳氢同位素指标,该区天然气可划分为油型气、煤型气和生物气3种类型,整个盆地形成了柴西油型气、柴北缘煤型气和柴东生物气3套含气系统。通过对盆地天然气基本特征的研究,分析了资源潜力及勘探程度,提出了“立足生物气,突破热解气”的下步勘探思路,指出下步应以柴东水溶气及浅层气、柴西北区热解气作为重点勘探目标。Qaidam Basin is the fourth largest gas-bearing region in China, of which the natural gas can be classified into oil-type gas, coal-type gas and biogas according to the carbon and hydrogen isotopic index. There are three suites of gas-bearing systems developed in the basin including the oil-type gas system in the northwestern area, the coal-type gas system in the northern margin, and the biogas system in the eastern area. Based on the research on the basic characteristics of the natural gas in the basin and the analysis of its resources potential and exploration degree, the thinking for next exploration is proposed as òputting the foothold on biogas and making a breakthrough in pyrolysis gas. It is suggested that the water-soluble gas and shallow gas in the eastern region and the pyrolysis gas in the northwestern region be the key targets for exploration.
