Geothermal exploitation and irrigation well system

The utility model discloses a geothermal exploitation and recharge well system which comprises a recharge well, a recharge device and an exploitation well, the recharge well and the exploitation well are suitable for extending into a geothermal reservoir, and the recharge well is provided with a recharge sleeve extending into the geothermal reservoir. At least part of the recharge device is arranged in the recharge well, and the recharge device can enable the geothermal reservoir outside the recharge sleeve to form a fracturing crack. The mining well is formed after the fracturing crack is formed, and the mining well is arranged in the extending direction of at least one fracturing crack. The recharge device forms a fracturing crack in the geothermal reservoir outside the recharge sleeve, so that the porosity and permeability of the geothermal reservoir are improved, smooth flow of recharge water can be ensured, the recharge amount of a recharge well is improved, and the recharge efficiency is improved.
