Anti-corrosion two-stage sealing injection-production packer for air energy storage well

The invention relates to the technical field of injection and production of air energy storage wells, in particular to an anti-corrosion two-stage sealing injection and production packer for an air energy storage well, which is used for solving the problem of premature leakage caused by corrosion of an existing packer. The packer comprises a rubber cylinder sealing mechanism arranged on the upper portion of the injection-production packer and a metal sealing mechanism arranged on the lower portion of the injection-production packer. An anchoring mechanism is arranged in the middle of the injection-production packer; when the rubber cylinder sealing mechanism and the metal sealing mechanism are started, the anchoring mechanism can be protected; the anchoring mechanism of the packer and key components of the rubber cylinder sealing mechanism and the metal sealing mechanism are located between the two sealing mechanisms, after the two sealing mechanisms are started, it can be guaranteed that the anchoring mechan
