Abstract

Abstract:

Reinjection plays a crucial role in maintaining the pressure of geothermal reservoirs, extending the lifespan of geothermal fields and preserving the environment. In the Hancheng area, located at the southeastern margin of the Ordos Basin in Shaanxi province, there is an abundance of karst geothermal resources. Despite this, the level of development and utilization of these resources in the region remains relatively limited. To further evaluate the development potential of Karst geothermal resources in the region, we implemented a karst geothermal heating project and conducting a tracer test, employing NH₄SCN as the tracer. The goal was to establish an hydraulic connection between the production well and the reinjection well. Utilizing the thermal breakthrough model, predictions were made regarding the changes in the temperature of the production well as a consequence of long-term reinjection. The findings suggest that there is a primary direct pathway for the flow of water, and possibly a secondary path that may contribute to groundwater storage. The temperature of production well's water is projected to decline by 8.31 ℃ over 100 years due to the reinjection process. However, this decline is not expected to cause a severe temperature drop in the geothermal reservoir within this dual-well system.

Key words: Ordos basin, karst geothermal, double wells reinjection, tracer test, production well temperature
