利用奇村地热田地下水水化学资料,根据Na-K-Mg平衡图解法和Phreeqc水文地球化学模拟软件计算的地下水中矿物饱和指数结果,认为奇村地热田地下热水处于未饱和状态,或者是受到了冷水的混合。这说明地下热水已经开采过量,应该控制、统筹规划地下热水的开采,不然将会降低地热田的使用寿命。
According to the results of mineral saturation index of groundwater calculated by Na-K-Mg equilibrium diagram and Phreeqc hydrogeochemistry simulation software, the underground hot water in Qicun geothermal field is not saturated or Got cold water mix. This shows that the underground hot water has been mined too much, and the underground hot water exploitation should be controlled and co-ordinated. Otherwise, the service life of the geothermal field will be reduced.
