摘要:

以海拉尔-塔木察格盆地中部断陷带C02气藏中的C02为研究对象.通过组分分析、碳同位素及氦、氩同位素分析,结合研究区C02含量和同位素数据及他人研究成果,利用排除法探讨研究区C02的成因及来源。结果表明: 研究KC02平均含最大于85%，C02稳定碳同位素偏轻,Sl3CeC):^-13. 1釦一8. 8知,为fl前已发现的具有较为特殊碳同位素组成特征的C02气藏;尽管C02稳定碳同位素偏轻，但通过排除法可以证明该K C02为无机成因气的结论最为合理,且C02应来源于上地幔岩浆脱气。

Abstract:

Based on the research of the C02 gas reservoir in the middle fault zone of Hailaer-Tamtsag Basin, the origin of C02 was researched using the exclusive method by composition analysis of carbon, helium and argon isotope，data of C02 amount and the research achievements of C02 gas by the scholars. The results show that the average content of C02 in the study area is more than 85% , and the value of the 5¹³Cco，ranges from -13. \%v to -8. 8%f. With the characteristic of light
