摘要
本文通过对准噶尔盆地西北缘典型煤型气和油型气的人工混合实验，测定和分析了不同比例混合气中轻烃组成及碳同位素的变化，求得和建立了混合比与二甲基环戊烷含量及δ１３Ｃ１之间的相关式和经验图版，从而为今后估算混合气中煤型气和油型气的相对贡献提供了定量依据。本文还对该区混合气藏形成的地质条件进行了探讨。
By an analysis of an artificially mixed typical coal type gas and oil type gas samples fromthose occurred in the northwest boarder of Junggar basin, this paper gives the variation oflight hydrocarbons and carbon isotopes for the gases mixed at different proportions. Correlation expressions and empirical plots of dimethylcyclopentane as well as isotope δ13C vs. mixedratio are established, and thus, a basis for an estimation of relative contributions of coal typegas and oil type gas in any mixed gas in a reservoir can be estimated quantitatively. This paper gives a discussion of the geological conditions for the formation of such mixed gas reservoirs also.
