First of all, in terms of resource reserves and quality, although there is helium in our basin, the content found so far is still too small compared with the world, only 11×10^8 cubic meters, accounting for about 2.1% of the global total . In contrast, the consumption of helium in my country has an average growth rate of 11% from 2014 to 2018. It can be seen that China's helium reserves are not enough to support huge consumption. Even if it is developed, most of it still needs to rely on imports. Moreover, the quality of the currently explored helium is relatively poor, not reaching the commercial level, and even if it is mined, it cannot be used. The second is the issue of development equipment and efficiency, from the perspective of natural gas helium extraction equipment. There are very few helium extraction devices in my country, such as Dongxingchang Town, Rongxian County, Sichuan Province. This device was rebuilt in 2011 and is responsible for the purification of helium. The purity of crude helium produced is about 80%. Then the crude helium needs to be transported to Chengdu Natural Gas Chemical Plant for further purification, with an annual output of 20×10^4 cubic meters of pure helium. Therefore, the equipment and purification efficiency also make it difficult for us to produce helium by ourselves, so we can only rely on imports.
