THE GENESIS OF MOLECULAR NITROGEN OF NATURALGASES AND ITS EXPLORATION RISK COEFFICEIENT IN TARIM BASIN
塔里木盆地天然气中氮气成因与油气勘探风险分析

Molecular nitrogen is one of most common non-hydrocarbon components in natural gas reservoirs. The origin of molecular nitrogen in natural gas can be classified to be three types, according to its origin, that is, atmospheric nitrogen resource, bio-genesis resource and deep crust and upper-mantle resource correspondingly. Based on the nitrogen preserve, distribution and some geochemistry properties, and combined with the volcanic history of Tarim basin, the genesis of molecular nitrogen in natural gas has b...
