Claim 0:
1. A double-response self-degradable temporary plugging agent, which is prepared by polymerization of raw materials comprising, in parts by weight, 32 parts of a monomer, 1-5 parts of a reinforcing agent, 0.1-0.6 parts of a dispersant, 0.07-0.12 parts of an initiator, 2-10 parts of a hydrophobic nano-powder and 60-90 parts of water, wherein
the monomer comprises a first monomer and a second monomer, wherein the first monomer is at least one selected from the group consisting of a propylene monomer, a styrene monomer, itaconic acid, acrylic acid and maleic anhydride, and the second monomer is a temperature-sensitive degradable crosslinkable monomer, being at least one selected from the group consisting of 1,4-butanediol dimethacrylate, ethylene dimethacrylate and a poly(ethylene glycol) diacrylate; and
the reinforcing agent is an acid-sensitive material.
