摘　　要：氦气为重要的稀有战略资源,近年来其重要性逐步得到相关业界和政府部门的高度重视。为了解青海省氦气资源前景,通过对省内主要盆地含氦情况调查研究,结合已有研究进展及成果,较系统的开展了全省氦气资源潜力评价。研究认为,青海省氦气资源成藏类型初步可划分为3大类、6小类,主要包含游离气藏(天然气伴生气藏、页岩气伴生气藏、煤层气伴生气藏、氮气伴生气藏)、水溶气藏、自生自储气藏;省内氦气藏点主要集中在柴达木盆地、共和盆地、南祁连盆地、八宝山盆地及巴颜喀拉残留洋盆等;青海省盆地主要以典型壳源气成因为主,次为幔源氦;将青海省氦气资源成藏模式归为3种:古老地层水上移释氦富集模式、天然气沿古老储集层运移富氦模式、古老地层水富集模式。Helium,as an important rare strategic resource,has gradually received high attention from relevant industries and government departments in recent years.To understand the prospects of helium resources in Qinghai Province,this article conducts a systematic evaluation of the province's helium resource potential through investigation and research on the helium content in major basins within the province,combined with existing research progress and achievements in the province.Research suggests that the types of helium gas reservoirs in Qinghai Province can be preliminarily divided into three categories and six subcategories,mainly including free gas reservoirs(natural gas associated gas reservoirs,shale gas associated gas reservoirs,coalbed gas associated gas reservoirs,nitrogen associated gas reservoirs),water-soluble gas reservoirs,and self generated and self stored gas reservoirs;The helium gas reservoirs in the province are mainly concentrated in sedimentary basins such as the Qaidam Basin,the Gonghe Basin,the South Qilian Basin,the Babaoshan Basin,and the Bayan Kara Residual Ocean Basin;The main genesis of various basins in Qinghai Province is typical crustal gas,followed by mantle derived helium;The helium resource accumulation patterns in Qinghai Province can be classified into three types:the ancient formation water migration and release helium enrichment pattern,the natural gas migration and helium enrichment pattern along the ancient reservoir layer,and the ancient formation water enrichment pattern.
