塔北天然气组分特征及同位素组成

Characters of Composition and Isotopic Composition of Natural Gases in Northern Tarim

通过对塔北天然气３２个样品的化学组分特征，甲烷的碳、氢同位素组成及关系，以及单烃碳同位素系列特征，甲烷的碳同位素组成与烃类组分关系等方面的综合研究揭示了塔北不同油气区不同井位天然气的成因类型以及某些井位天然气的来源，为塔北油气勘探提供了有价值的信息。

By means of the study on the 32 sample′s characters of composition, isotopes of carbon and hydrogen and serial isotopes of hydrocarbons, on the isotopic relationship of carbon and hydrogen, on the relationship between hydrocarbonic composition and isotopes of carbon from methane, the paper gets new knowleges about natural gases' genetic type of different wells in different oil andgases fields as well as the origin of some natural gas depositions in Northern Tarim, and supplies available information for exploration of oil and natural gases.
