摘要
Ground water source heat pump (GWHP) system is used in the test field. The influence of GWHP on regional geothermal field is analyzed based on the temperature of groundwater which is continuously monitored during the running course of the system. It is found that groundwater temperature of the area around pumping and recharge wells has a significant change in this process. Injection water will be stored in the aquifer with anomalous edge lens. Because of the thermal cumulative effect, gathering of hot and cold water body around the water-bearing stratum and the aquifuge will occur after a running circle of the system, even if it is a load balance.
