Abstract: A multilevel deep well cooling and geothermal utilization system and process. The system has a deep well heat harnessing system, a shallow part heat-exchanging system, and a high-temperature water lifting system. The deep well heat harnessing system has a heat absorbing pipe, a thermally-conductive fluid lifting pipe, a thermally-conductive fluid lowering pipe, temperature sensors, and a water pump. The shallow part heat-exchanging system has a heat-dissipating pipe, a heat-storing water pool, a water intake pump, a water intake valve, a temperature sensor and a liquid level meter. The high-temperature water lifting system has a water discharging pump, a flowmeter, a water discharging valve, and a high-temperature water lifting pipe.
