Special Issue Information
Dear Colleagues,
Geothermal resources are valuable clean and recyclable renewable resources with great utilization value; they can be widely used in various fields such as power generation, heating, physiotherapy, greenhouse, and aquaculture. In their natural state, geothermal resources have the characteristics of deep burial, slow groundwater recharge, and slow regeneration.
In order to maintain the pressure of thermal storage, avoid the continuous decline in water level caused by long-term, large-scale exploitation of geothermal water, and realize the sustainable utilization of geothermal water, the surface clean water source or used geothermal tail water is reinjected into the thermal reservoir through the recharge well; this can achieve the goals of increasing the mining output of geothermal resources, alleviating the continuous decline in groundwater level, and reducing the environmental pollution caused by direct discharge of geothermal fluid. Thus, it is an effective means to ensure the sustainable development and utilization of geothermal energy.
Although geothermal water reinjection can increase the artificial supply source, can efficiently replenish the consumed groundwater resources, has a role in improving the geothermal mining output, maintains the pressure of heat storage, and alleviates the decline in groundwater level, etc., disorderly and excessive geothermal reinjection may accelerate the emergence of "thermal breakthrough", resulting in irreversible changes in the geothermal field, temperature field, water flow field, and chemical field. Therefore, it is necessary to strengthen the dynamic monitoring of geothermal water and the study of its dynamic characteristics during reinjection.
This Special Issue is organized into three sections:
Section 1: Origin of Geothermal Water: Studying the origins of geothermal water can elucidate the characteristics of geothermal water recharge, runoff, and discharge, which is very important for the monitoring of geothermal water.
Section 2: Hydrochemical Research: The dynamic monitoring and analysis of the chemical composition of geothermal water are very important to understand the change in the chemical composition of geothermal water.
Section 3: Monitoring of Fractured Rock Aquifers: By monitoring fractured aquifers and strengthening the dynamic monitoring of geothermal water and the study of its dynamic characteristics, the characteristics of the geothermal water temperature field, flow field, and chemical field can be dynamically understood.
