摘要:

通过对关中盆地地热井中地下热水的同位素和水化学成分分析,结合研究区的地热地质和水文地质条件,进行了地下热水补给时的温度研究,结果表明,关中盆地地下热水接受补给时的温度以西安地区最低,咸阳次之。同时应用Na-K-Mg三角图和水化学平衡温度理论的方法,估算在平衡条件下关中盆地最大热储温度为118℃。热储温度计算结果表明,关中盆地腹部应为中低温热储层。

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.
