| description | The invention relates to a layered gravel filling pumping and filling same-well system, and belongs to the field of geothermal energy utilization. The layered gravel filling pumping and filling same-well system comprises a layered gravel filling pumping and filling same well, a water pumping area, a partition area, a water return area, a water pumping gravel backfilling area, a partition gravel backfilling area, a water return gravel backfilling area, a water return centrifugal drainage plate, a heat exchanger, a sand remover, a water pump and a flow regulating valve. The system has the advantages that the porosity of the partition gravel backfilling area is far smaller than that of the water pumping gravel backfilling area and the water return gravel backfilling area, the amount of return water permeating into the water pumping area from the partition gravel backfilling area is reduced, the flow through occurrence strength is reduced, the system efficiency is improved, and the service life is prolonged; and |
