| 摘 要： | 即墨温泉是一种含多种化学元素的高矿化度热水资源，在深部地下热水沿断裂带上涌的过程中可能与浅部冷水发生不同程度的混合，使开采获得的地热水水质也发生了相应的变化。对即墨温泉地热资源核心开采区2口开采深度不同的地热井进行了为期1个水文年的水质变化监测，地热水水质参数上半年比下半年高，水质参数发生急剧变化的时间相对于气候的季节性变化有2～3个月的滞后，且氯度、矿化度和电导率的季节性变化幅度在开采深度较浅的水井中较大，表明开采条件和区域性气候条件的变化共同控制了地热水水质变化。

| Abstract: | Jimo hotspring is one of high mineralized geothermal resources with many kinds of chemical components enriched in the geothermal water. During the period of hot water upwelling along the tectonic faults , the hot water in deep part can be mixed with cold water. The quality of exploiting hot water has a relative change. In this work, two exploited wells with different exploitation depth are observed one year arounding Jimo hot spring in order to study the dynamic changes of water quality. According to the acquired datas, the contents of water quality parame- ters are high during the first half year and low during the last half year. The abrupt changes of water quality param- eters show 2 - 3 months delay in comparison with the local precipitation changes. The seasonal changes of chlorinity, conductivity and the total dissolved solid content in the exploited water are more notable in the well with deeper exploitation depth. It is indicated that both the exploitation depth and local climate have influence on the water quality of exploited water to Jimo hot springs geothermal resource. |
