鲁东构造型地热田回灌过程中压力对回灌量的影响研究——以威海市宝泉汤为例

Study on Recharge Effect of Pressure to Recirculation Volume in Recharge Process of Tectonic Geothermal Field in Ludong Area——Setting Baoquan Spring in Weihai City as an Example

摘要:

鲁东出露有多处温泉，且开发历史较久，均为典型的构造裂隙型地热田。近年来随着开采规模的日益增加，热储压力不断降低，温泉已不自涌，水位、水温逐渐降低，为实现其可持续利用，对其进行回灌势在必行，为此进行了回灌试验，在回灌试验中压力对回灌量的变化有较大的影响，该文详细的论述了其影响的程度及变化，得出了基本的结论。

Abstract:

A number of hot springs exposed in Ludong area with long development history. They are typical tectonic fissure type geothermal field. In recent years, accompanying with increased mining scale, thermal reservoir pressure has decreased continuouly. Hot springs can not spew any longer, and water level and water temperature decreased gradually. It is very necessary to carry out recharge in order to realize sustainable utilization. In this recharge test, pressure has large influence to recharge volumes. In this paper, the level and change of its influence have been discussed in detail , and gained the basic conclusion.
