摘要： 根据准嘴尔盆地南缘和腹部的地面气苗、井下气层气、油层伴生气的组分、碳同位紊系列及轻灶组成的研究, 认为它们来源于休罗系煤系地层腐技型毋质生成的煤型气。在后期的改造和演化中, 有些煤型气透受细菌的氧化和降解, 形成生物降解气; 有些则与同源不同成熟期的天然气发生混合作用。

Abstract: According to the study of the composition, carbon isotopes and light hydtocarbons'composition of gas seepage,Bas reservoir gas and associated gas in the south margin and hinterland of Junggar Basin, it is considered that they were coal type gas derived from the humic organic matter in the Jurassic coal measures. In the later transformation and evolution, some were oxidided and biodegraded, some were mixed up with the gas with the same source and different maturity.

Key words: Junggar Basin, Natural gas, Genetic type, Gas source
