| 摘 要： | 鉴于菏泽市目前地热资源开发利用现状,随着地热井数量的增多,地热水开采量逐年增大,导致地热水水位呈逐年下降的趋势,为了保护这一绿色清洁能源,缓解地热资源过度开发造成的地热水水位持续下降、尾水外排污染水、土体等一系列负面影响,有必要采取地热尾水回灌措施,来保证地热资源的可持续发展。采用地球物理勘探,地热井钻探、单孔及对孔抽水试验、回灌试验及水质测试等方法,分析了回灌对水位、水温的影响,分析结果认为回灌对水温、水质影响不大。在回灌量相同的条件下,回灌尾水水温越低,回灌的升幅越小,回灌越容易。经综合分析认为,菏泽市城区奥陶系回灌效果良好,回灌潜力巨大,在菏泽市奥陶系热储中进行回灌是可行的。

| Abstract: | In view of present condition of development and utilization of geothermal water in Heze city, accompanying with the increasing number of geothermal wells, geothermal groundwater exploitation has been increasing, and the water level has declined rapidly. In order to alleviate a series of negative effects caused by over-exploitation of geothermal resources, such as the continuous decline of geothermal water level, the contaminated water discharged from tail water and soil mass, it is necessary to take measures of geothermal tail water recharge to ensure sustainable development of geothermal resources. The effects of recharge on water level and water temperature have been analyzed by geophysical exploration, geothermal well drilling, single hole and hole pumping test, recharge test and water quality test. It is showed that recharge has little effect on water temperature and water quality. Under the condition of the same amount of reinjection, the lower the tail water temperature, the smaller the rise of reinjection, and the easier the reinjection. The recharge effect in Ordovician thermal reservoir is good and feasible, and the recharge potential is great in Heze city. |
