通过甲烷及其同系物的碳同位素判别分析、无机气组份差别分析以及δ1 3C1-R o关系三种方法对渝东南地区五口钻井的天然气组分、烷烃碳同位素以及有机质成熟度研究成因类型。并通过图版和图表方式给出了判别煤成气与油型气的简易方式。
Through the carbon isotope discrimination analysis of methane and its homologues, the differential analysis of inorganic gas components and the relationship of δ1 3C1-R o, the gas composition, alkane carbon isotopes and maturity of organic matter of five wells in Southeast Chongqing were studied. . The simplified method of judging the coal gas and the oil gas by chart and chart is given.
