| description | The invention relates to an evaluation method considering geothermal water recharge capacity reduction caused by migration and blockage of stratum silt particles, and belongs to the technical field ofgeothermal water recharge. The method mainly solves the problems that in the geothermal water recharging process, and the stratum particle migration blockage risk and the reduction of the rechargingcapacity are judged. The key technical points of the method comprises: calculating the recharge amount and the water flow rate at different radiuses of a near-well stratum according to the displacement pressure difference between a recharge well bottom and a geothermal reservoir; and then dividing a near-well formation flow velocity profile into four subareas according to the determined starting water flow velocity of the movable silt particles with different particle sizes and the determined near-well formation water flow velocity, determining the migration and deposition amount of the silt particles in each subarea, |
