ON THE ORIGIN OF THE NATURAL GAS IN THE NORTHERN TARIM BASIN
-
摘要: 作者综合利用天然气碳同位素、C6～C7,轻烃组成以及化学组成资料,对塔里木盆地北部天然气的成因类型进行研究,提出了塔北天然气各种成因类型和成熟度的判识标志。认为塔北天然气主体属高熟腐泥型气,气源岩主要为寒武-奥陶系。陆相成因的成熟腐殖型气和深源混合气也有发现,并具有一定的资源前景。Abstract: The authors of this paper study the original types of the natural gas in the Northern Tarim Basin on the basis of the carbon isotopic data of light hydrocarbons C6～C7 and their chemical compositions. At the sametime,it is proposed the original types and the discriminating criteria, such as maturity etc. for the natural gas in the Northern Tarim Basin.
