摘　　要：普光气田是四川盆地近期发现的规模最大、埋藏最深、资源丰度最高的气田。通过对普光气田天然气组分和碳同位素的分析,普光气田是一个高含硫化氢的干气田,普光气田天然气组分以烷烃气为主,平均含量占总体积的78.37%;非烃气体以H2S和CO2为主,平均含量分别占12.63%和8.71%。烃类气体以甲烷占绝对优势,平均含量为79.81%;干燥系数均很大。普光气田天然气主要体现出油型气的特征,CO2的δ13C具有无机成因的特征。The Puguang gas field is a gas field with the largest scale,buried depths and oil-gas reserves in the Sichuan Basin,based on study of the component and its carbon isotope of natural gas samples from the Puguang gas field.The Puguang gas field is the high H2S-bearing natural gas.Natural gas in Puguang gas field is mainly composed of hydrocarbon gas with an average content of 78.37%;The non-hydrocarbon gas is mainly composed of H2S and CO2 with average contents of 12.63% and 8.71%.Hydrocarbon gas is mainly co...
