青海省水溶氦气资源现状及赋存特征
Current Status and Occurrence Characteristics of Water-soluble Helium Resources in Qinghai Province
摘要
Abstract
As a special type of helium reservoir,water-soluble helium has gradually received widespread atten-tion in recent years.Qinghai Province has a vast territory and abundant groundwater resources such as hot springs.Through a systematic investigation of hot springs,cold springs,and brine,the distribution,content,ge-netic characteristics,and relationship with temperature and mineralization of water-soluble helium resources were systematically explored.Research has shown that the distribution of water-soluble helium resources in Qinghai Province is closely related to intrusive rocks,mainly distributed in the Qaidam Basin,Gonghe Basin,Maduo Region,and South Qilian Basin.Among them,the Qaidam Basin has the highest water-soluble helium content,up to 1.1%;Estimate the helium production in the Qaidam Basin,Gonghe Basin,Maduo Region,and South Qilian Basin,which are 39.49×108 m3,2.16×108 m3,1.46×108 m3,and the R/Ra is 0.003～0.068,indi-cating a typical crustal origin gas;The helium content is weakly positively correlated with temperature and posi-tively correlated with mineralization,and hot springs with water temperature greater than 25℃and saline water with mineralization greater than 1 g/l are favorable environments for the occurrence of water-soluble helium re-sources in Qinghai Province.关键词
