摘要
根据准噶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、碳同位素系列及轻烃组成的研究,认为它们来源于侏罗系煤系地层腐殖型母质生成的煤型气。在后期的改造和演化中,有些煤型气遭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。
According to the study of the composition, carbon isotopes and light hydrocarbons' composition of gas seepage,gas reservoir gas and associated gas in the south margin and hinterland of Junggar Basin, it is considered that theywere coal type gas derived from the humic organic matter in the Jurassic coal measures. In the later transformationand evolution, some were oxidided and biodegraded, some were mixed up with the gas with the same source and dif-ferent maturity.
