When production needs, the technology of aquifer thermal energy storage (ATES) can achieve cooling or heating by running the “underground cold water reservoir” or the “underground heat water reservoir”. In this paper, taking Sanhejian Coal Mine as an example, we discuss that with the same pumping and irrigation flow in multi-wells, distribution and change of temperature field in aquifers when energy storage system runs. The simulation results of aquifer temperature field show that any cold water well running can make temperature around the centerlin rise, and the rate rose from 0.4 °C to 6 °C as time increases. Any cold water well running can make the lowest temperature of other cold water wells around it rise 0.4°C or 0.5°C, the temperature of the aquifer whose temperature is below 15°C rises about 1°C or 2°C. It proves that the distance of wells is reasonable. When the whole system runs, the temperature field of 2°C to 10°C change greatly, the temperature field of 10°C to 15°C is stable, which is less affected by heat energy consumption in cold water well.
