Regularity Prediction & Analysis of Water-heat Transportation between Production & Injection Wells
The study on the water-heat transportation of aquifer is theoretically signifieant for the application of Groundwater Heat Pump (GWHP) system.According to relative eoncepts of Hydrogeology and seepage mechanics in porous medium, a mathematical model of thermal transportation in aquifer is established. The velocity fields, head pressure fields and temperature fields of two groups of pump-injection wells have been obtained.The following conclusions are obtained by eomputation and analysis: ① In the state of pumping and injection, head pressure changes faster than temperature and its incidence is larger, while the incidence of temperature field is smaller, and its change rate is lower and not evident. ② The radius of temperature field is mainlyless than 50 meters from the well center. The average temperature gradient is 0.10℃/m. ③The temperature change of further observation wells caused by injection costs more time,and the change is not evident.
