Abstract:Carrying out geothermal monitoring is an important basic work in the development and utilization of geothermal resources. and it is also an important means to understand the dynamic changes of regional geothermal resources。 Conventional geothermal mining monitoring uses monitoring equipment installed in mining wells and recharge wells to obtain dynamic parameter information such as water temperature, flow rate, wellhead pressure, water level, and water quality during geothermal mining and recharge. Affected by various factors, such as the well diameter of the production well and the recharge well, the diameter of the pumping equipment, the diameter of the flange, the pump, the pump, the backup and other factors, it is easy to cause difficulties in the installation of the monitoring equipment and the possibility of damage and risk, which cannot obtain stable longterm monitoring data, and the obtained monitoring data have errors. Based on years of monitoring practice, classified monitoring methods for regional geothermal exploitation has been put forward. Users are responsible for monitoring and transmitting water volume, water temperature and water quality during geothermal exploitation and reinjection. The management department is responsible for obtaining regional water level, water temperature, water quality and other information through monitoring of special geothermal monitoring wells. Both of them have their own responsibilities and complement each other. They can obtain longterm, stable and accurate geothermal water level, water temperature, water volume and water quality monitoring data, Provide effective monitoring data for geothermal management.
