Abstract:
By analyzing the isotope and the data of hydrochemistry composition of geothermal water from the geothermal wells in Guanzhong basin, and the conditions of geothermal geology and hydrogeology in the area, the making-up temperature of geothermal water is researched. The results show that the lowest making-up temperature of the geothermal water in Guanzhong basin is in Xi'an, and Xianyang has a lower making-up temperature than Xi'an. With the method of Na-K-Mg triangular diagram and hydrochemistry balance temperature theory, it is estimated that the maximum thermal reservoir temperature in Guanzhong basin is 118 ℃ in equilibrium condition. From the calculation results of temperature, the center of Guanzhong basin should be mesothermal and microtherm reservoir.
