The plugging agent comprising the following raw materials in parts by mass: 20 to 40 parts of a polymeric monomer, 5 to 10 parts of a biopolymer, 0.1 to 1.0 part of a cross-linking agent, 50 to 70 parts of a reinforcing agent, 0.01 to 0.05 part of a gel breaker and 0.001 to 0.003 part of an initiator, wherein the polymeric monomer is selected from a mixture of acrylamide and methacrylamide; the biopolymer is one selected from xanthan gum and guar gum; the cross-linking agent is selected from ethylene glycol dimethacrylate; the reinforcing agent is one or a mixture of more than one selected from potassium chloride, sodium chloride, sodium nitrate and potassium nitrate; the gel breaker is a mixture of benzoyl peroxide and ferrous sulfate, and a molar ratio of benzoyl peroxide to ferrous sulfate is (1-2): 1; and the initiator is 1-((cyano-1-methylethyl)azo)formamide. The plugging agent has the advantages that pressure-bearing strength is good, self-degradation release can be realized, and damage to a stratum is small.
