To study the effect of aquifer’s hydro geological conditions on standing column well(SCW),the operating characteristics of SCW under different hydro geological parameters were analyzed through large numbers of calculation cases.The results show that the aquifer with larger horizontal permeability coefficient enhances the ratio of original groundwater exchange and lightens the change of pumping temperature.The aquifer stagnant thermal conductivity has little effect on pumping temperature if SCW is in the aquifer with good permeability,however,if with poor permeability,the pumping temperature would be rapidly increased with the increase of the aquifer stagnant thermal conductivity.The permeability coefficient is a key parameter to influence the change extent of pumping temperature obviously.
