Physical simulation experiments on competitive dissolution of helium in helium-containing to helium-rich gas reservoirs

Meitian dizhi yu kantan
Background and Purpose Helium is widely applied in high-tech and scientific research fields due to its unique physicochemical properties. Formation water plays a key role in helium migration and enrichment. Typically, in the form of dissolved gas, helium is transported in pores or fractures by formation water. When helium-rich fluids migrate to shallow
