松辽盆地天然气中氦气的检测与提纯方法

氦气是国防军工和高科技产业发展不可或缺的稀有战略性物资之一。我国氦气资源相当贫乏,氦气基本上从美国进口。虽然天然气中氦气质量分数比较低,提取难度大,但是含氦天然气迄今仍是工业化生产氦气的唯一来源。因此,研究建立适合油气田天然气中氦气检测与提纯技术,为从天然气中提取氦气提供科学依据,具有十分重要的意义。采用气相色谱分析技术对松辽盆地天然气中氦气进行定量分析。松辽盆地天然气中氦气的质量分数比较低,但比较稳定

Detection and Purification of Helium in Natural Gas of Songliao Basin

Helium is one of the rare strategic materials indispensable to the development of national defense and high⁃tech industries. Helium resources in China are quite poor, and helium is basically imported from the United States. Although helium content in natural gas is relatively low and difficult to extract, natural gas is still the only source of industrial production of helium. Therefore, it is great significance to study and establish a suitable technology for the determination of helium content in natural gas in oilfield, and to provide a scientific basis for the extraction of helium from natural gas. Gas chromatographic method is used to survey and quantitative analysize the helium content in natural gas from Songliao basin. The helium content in natural gas from Songliao basin is relatively low, but the content is relatively stable
