摘要
氦气是重要的稀有战略资源,目前主要来自天然气。氦气如何在气藏中富集是当前研究热点,也是氦气勘探迫切需要解决的关键问题。在柴达木盆地、四川盆地和准噶尔盆地采集天然气样品进行氦气和氮气含量测试及分析,并结合对其他国内外主要富氦气田天然气组分和氦气含量研究,发现富氦气田中氦气含量与氮气具有很好的相关性。不仅如此,一些贫氦气田也存在该现象。据此,提出氦气富集与氮气具有耦合作用,二者同时在天然气中富集,都与地下水有关,可能来自相同的源岩。氦气与氮气耦合关系的提出,或许能够真正找到氦气富集的奥秘,为寻找富氦资源打开新思路,为氦气富集理论提供依据。
Helium is an important rare strategic resource,mainly from natural gas.How helium is enriched in gas reservoirs is currently a hot research topic and a key issue that needs to be urgently addressed in helium exploration.Natural gas samples were collected from Qaidam Basin,Sichuan Basin and Junggar Basin for helium and nitrogen content testing and analysis,and combined with studies of natural gas fractions and helium content in other major helium-rich fields at home and abroad,it was found that the helium content in the helium-rich fields has a very good correlation with nitrogen.Not only that,but the phenomenon also exists in some helium-poor fields.Accordingly,it is proposed that helium enrichment is coupled to nitrogen,and that both are simulta-neously enriched in natural gas,both are associated with groundwater,and may be derived from the same source rocks.The proposed coupling relationship between helium and nitrogen may be able to really find the mystery of helium enrichment,open a new idea for the search for helium-rich resources,and provide a basis for helium enrichment theory.
