德州市城区地热水人工回灌试验研究

Study on Geothermal Re-injection Experiment in Districts in Dezhou City

摘要:

以德州市城区地热回灌为例，分析了地热回灌对水质、水量、水温的影响，证实了回灌井结构、热储特征、回灌压力、回灌工艺等是影响回灌效果的主要因素，明确了地热回灌量与出水量、回灌压力之间的关系，提出回灌可以有效解决地热开发利用带来的诸多问题。

Abstract:

Setting geothermal rejection in Dezhou districts as an example, effects of geothermal rejection to water quality, pumping rate and water temperature and elements which will effect re-injection efficiency are analysed. It is proved that the structure of re-injection well, geothermal reservoir characteristics, re-injection pressure and re-injection are major elements which will effect re-injection effect. Relationship between re-injection rate and re-injection pressure are determined as well in this paper. Through this experiment, it is proved that re-injection is an effective method in soluting problems caused by geothermal resource exploration.
