On the influencing mechanism of geothermal fluids on the dynamic changes of groundwater flow and heat transfer temperature

Abstract

Nowadays, people are paying increasing attention to the rational exploitation of geothermal resources. To develop and utilize geothermal resources in a scientific way, it is important to understand the change patterns of key geohydrological parameters such as seepage velocity and temperature. As part of the effort, this paper analyzes and studies the influencing mechanism of geothermal fluids on the dynamic changes of groundwater flow and heat transfer temperature. First, a differential equation of heat conduction of geothermal fluids and a groundwater flow-geothermal fluids thermal coupling model were constructed to study the seepage state and the heat transfer of groundwater flow in the energy extraction process. Then, an analytical model for the influence of groundwater seepage on heat transfixion was established, directly showing the relevant mechanism. The experimental results proved the effectiveness of the constructed model.
