咸阳城区热储流体混合作用研究及模拟计算

Studies of Mixing and Model Calculation of the Geothermal Systems in Xianyang

应用水文地球化学模拟方法对咸阳城区热储流体混合作用分析和混合比例的计算.结合研究区的地热地质和水文地质条件,进行地下热水混合作用和混合程度的研究.结果表明,咸阳城区地下热水在不同程度上都存在与较低温度地下热水的混合作用。应用PHREEQC模拟软件、稳定同位素D和温度计算热水与冷水的混合比例,估算在平衡条件下咸阳城区地下热水与冷水的混合比例在0.09～0.63之间。

Application of hydro-geochemical simulation method for geothermal fluid mixing analysis and calculation of the mixture ratio in Xian Yang.Combined with the geothermal geology and hydrogeology conditions,the geothermal water mixing and mixed degree for research.The research shows the geothermal water and the colder water existed different degree the mixing action in Xian Yang city.Application of PHREEQC software simulation,stable isotopes D and temperature calculation with the colder water mixture ratio of geothermal water,under the balance conditions,the geothermal water and the colder water of mixture ratio was between 0.09 and 0.63 proportions in Xian Yang city.
