| Abstract: | N 2 was separated from natural gases from the Tarim Basin by preparing GC and their isotopic ratios were determined. The nitrogen contents and isotopic ratios of the gases from different zones are different. The gases from the Tazhong, Tabei and Hetian river zones have higher nitrogen contents and lower nitrogen isotopic ratios whereas those from the Kuche zone show an opposite trend. The δ 15 N data of oils and gases from the Tarim Basin can be correlated, which suggests that there be inherent relationship between oil and gas from the same source rock. |
