The invention discloses an in-situ leaching production well reservoir transformation method which achieves the purpose of increasing yield and efficiency by reinforcing a production well sleeve at a reservoir to be transformed and injecting ore bed transformation liquid into the reservoir to be transformed to improve energy storage infiltration capacity. The invention further provides an in-situ leaching production well reservoir transformation system which comprises a sleeve unit and a pipe column unit, the reinforcing sleeve and a to-be-transformed reservoir are machined through the machining nozzle, then an annular space between the pipe column unit and the reinforcing sleeve is plugged through the upper packer and the lower packer, the well washing valve ball is put in, and the to-be-transformed reservoir is formed. The upper packer conveys ore bed transformation liquid into the installation cavity, the well washing valve ball blocks the communication channel, the shearing nail is cut off, the well washin
