The discovery of water soluble helium in
Weihe Basin was introduced in this paper. Researches showed that the water soluble helium resources are widely distributed and highly graded in Weihe Basin. The cause types of water-soluble gas are of different rock multi-source mixed characteristics, and the water soluble helium gas mainly comes from the shell source gas, with uranium rich granite being the main source rock. Four reservoir models build in deep basin geothermal water soluble helium; two kinds of methods to obtain the basin water soluble helium resources with quantity of (984.2~1 141.31)
