Investigation and Suggestions on Helium Resources in Qinghai Province
Helium,as an important rare strategic resource,has gradually received high attention from relevant indus-tries 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 re-search on the helium content in major basins within the province,combined with existing research progress and achieve-ments 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 reser-voirs,shale gas associated gas reservoirs,coalbed gas associated gas reservoirs,nitrogen associated gas reservoirs),wa-ter-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 Ba-baoshan 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 natu-ral gas migration and helium enrichment pattern along the ancient reservoir layer,and the ancient formation water enrich-ment pattern.
