Abstract
In hydrogeological work,hydrogeological parameters and groundwater quality are the key factors to determine the development and utilization of geothermal resources.In thie paper taking a geothermal well in Ganjun town of Zhangye city in Gansu province as an example,the permeability coefficient and influence radius of aquifer are calculated through a single hole steady flow pumping test and the groundwater quality is evaluated by comprehensive evaluation method through sampling and testing of groundwater.The results show that the permeability coefficient of Ganjun confined aquifer is 0.134 m/d and the in-fluence radius is 349.665 m.The comprehensive classification of groundwater quality is classified as Class Ⅳ,and the water quality is relatively poor and can be used as domestic drinking water after appropriate treatment.关键词
