Claim 4:
5. The geothermal heat utilization system according to claim 1,
wherein the first pipe includes a first pumping pipe extending into the first well at a first end,
wherein the second pipe includes a second pumping pipe extending into the second well at a first end,
wherein the first pipe includes a second water injection pipe extending into the second well at a second end,
wherein the second pipe includes a first water injection pipe extending into the first well at a second end,
wherein each pumping pipe of the first pumping pipe and the second pumping pipe includes an upper pumping port that opens such that the geothermal heat utilization system is capable of pumping water from the upper aquifer, a first opening and closing cylinder capable of opening and closing the upper pumping port, a lower pumping port that opens such that the geothermal heat utilization system is capable of pumping water from the lower aquifer, and a second opening and closing cylinder capable of opening and closing the lower pumping port, and
wherein each water injection pipe of the first water injection pipe and the second water injection pipe includes an upper water injection port that opens such that the geothermal heat utilization system is capable of injecting water into the upper aquifer, a third opening and closing cylinder capable of opening and closing the upper water injection port, a lower water injection port that opens such that the geothermal heat utilization system is capable of injecting water into the lower aquifer, and a fourth opening and closing cylinder capable of opening and closing the lower water injection port.
