Claim 10:
11. A method for preparing the double-response self-degradable temporary plugging agent as claimed in claim 1, comprising,
weighing each raw material according to the composition of the double-response self-degradable temporary plugging agent as claimed in claim 1;
dissolving the first monomer, the second monomer, the dispersant, the reinforcing agent, the hydrophobic nano-powder and the initiator in water to obtain a liquid mixture, and stirring the liquid mixture, to obtain a dried mixture; and
subjecting the dried mixture to a polymerization at a temperature of 30-60° C., to obtain a dry powdery microsphere including the double-response self-degradable temporary plugging agent.
