摘要： 地下热水的大量开采, 对水化学观测已产生严重的影响。 在开采的初期, 水化学观测受其影响并不明显, 而随开采时间的延续影响会越来越显著。 地下水的压力、 温度在这一变化过程中占主导地位, 所以在水化学观测过程中, 对井孔状态的监测至关重要。 该文试从地下水动力条件和热动力条件两方面对其影响机理进行了初步探讨。

Abstract: With the large-scale mining of geothermal water, it has made great influence on the chemical observation of underground water. This paper aims at preliminary discussion on the mechanism from two aspects, which may cause the influence: underground hydrodynamic condition and thermal-dynamical condition. On the initial period of mining, it was not obvious. The longer the mining continues, the more obvious the influence will cause. The underground water's pressure and temperature plays a dominant role on that variation process, so it is crucial to monitor well's situation on the water's chemical observation.
