摘　　要：氦气是重要的战略资源,中国氦气对外依存度超过95%,资源供需矛盾十分突出,亟需开展相关资源评价与研究。四川盆地是中国最早实现氦气商业利用的地区,但全盆地氦气资源调查研究水平依然薄弱。笔者梳理总结了目前四川盆地及周缘氦气勘探进展与资源现状,认为四川盆地及周缘地区含氦天然气具有分布广泛、层位众多的特点;高放射性泥页、基底花岗岩与铀矿岩层发育,具备氦气源岩基础;分析了四川盆地及周缘氦气资源潜力,总结了氦气勘探面临的主要问题,并根据氦气富集特征分析了未来氦气调查研究的重点方向,包括围绕四川盆地及周缘开展常规天然气田和页岩气藏含氦特征调查,建立天然气含氦特征数据库(集),开展氦气分布特征和氦气富集机理研究,以期为后续氦气勘探奠定坚实基础。Helium is a very important strategic resource.As our helium gas external dependency has been more than 95%,the contradiction between the supply and demand of helium resources is very prominent.Thus the related helium resource evaluation needs to be carried out as soon as possible.In this paper,the authors summarized the present situation of helium gas exploration and the helium resources in the Sichuan basin and its surrounding areas.As the Sichuan Basin is the first region to realize the commercial utilization of helium gas in China.The helium-bearing natural gas is widely distributed in Sichuan Basin and its surrounding areas horizontal and vertically.The highly radioactive shale formation,basement granite,and uranium rock are developed,which have the common basis as helium source rock.Finally,the helium gas resource potential in the Sichuan basin and its adjacent areas were analyzed in this paper.And the main problems for helium gas exploration were summarized.Based on the characteristics of helium gas enrichment,the future focus in the study of helium gas was also given.The authors suggested investigating and analyzing the characteristics of helium in conventional gas fields and Paleozoic shale gas reservoirs in and around the Sichuan basin,investigating the distribution characteristics of helium,and comprehensively analyzing the mechanism of helium enrichment by establishing the helium-bearing natural gas features data set,and exploring the genesis and distribution of helium.These works would help to lay a firm foundation for future helium exploration and exploitation.
