Based on collecting and analyzing the research results of China's helium resources,the authors have summarized the devel-opment and study of China's helium resources,and pointed out the research directions in the future.The helium's research history can be divided into four stages:cognitive stage,applied stage,basic research stage and extraction technique research stage.The distri-bution of helium gas in China has the characteristics of"small basins with full gas,large and medium basins with partial gas".The stra-ta hosting helium gas are Ordovician, Permian, Paleocene and Neocene strata. Composition characteristics show that the content of helium in nature gas is generally less than 1%,and only partial samples in Weihe Basin have high content that can reach 4.942%.Heli-um isotope analysis shows that the helium is mainly derived from crustal source with the addition of crust-mantle mixing source.The authors have reached the conclusion that the crustal helium gas and mantle helium gas are respectively affected by helium gas source rocks and deep fractures. It is suggested that more importance should be attached to crustal helium gas and that different methods should be adopted according to the different geneses.%通过对中国富氦天然气资源现有研究成果进行系统整理、分析,总结了中国富氦天然气研究的发展现状及进展,提出了未来中国氦气资源的研究方向.中国对氦气资源的研究历程可以划分为4个阶段:认知阶段、利用阶段、基础研究阶段及提取技术研究阶段.从分布规律看,中国富氦天然气分布具有小型盆地满盆含气、大中型盆地局部含气的特点,赋存层位以奥陶系、二叠系、古近系和新近系为主.组分特征表明,富氦天然气中氦气的含量普遍小于1%,仅渭河盆地部分样品氦气含量较高,最大值可达4.942%.氦同位素特征表明,中国氦气以壳源为主,壳幔混合为辅.分析认为,影响壳源氦分布的主控因素为氦气源岩,而影响幔源氦分布的主控因素为深大断裂.建议今后中国应以壳源氦研究为重点,针对不同区域不同成因的氦气,采用不同的研究方法.
