The double-response self-degradable temporary plugging agent is prepared by compounding a crosslinkable monomer with a temperature-sensitive degradability and an inorganic material with an acid solubility with a first monomer, a dispersant, an initiator and water, and subjecting the resulting mixture to a polymerization.
