NOVELTY - Preparing high-strength temporary plugging agent capable of realizing well zone seepage, comprises dispersing 0.5-2 pts. wt. hydrophilic nanomaterial in 1000 pts. wt. solvent, adding 30-50 pts. wt. glycerol allyl ether monomer, stirring or ultrasonicating for 0.5-3 hours, then adding 70-100 pts. wt. acrylamide monomer, stirring to dissolve, adding N,N'-methylenebisacrylamide, acrylate compound and initiator under stirring and continuous nitrogen flow conditions, reacting for 5-12 hours, and drying to obtain final product, where the acrylate compound is butanediol diacrylate, dipropylene glycol diacrylate or neopentyl glycol diacrylate, the mass ratio of N,N'-methylenebisacrylamide to acrylate compound is 1:5-12, and the amount of N,N'-methylenebisacrylamide is 0.08-0.15% of the total mass of the monomer. USE - The high-strength temporary plugging agent is useful for seepage volume fracturing in the well zone. ADVANTAGE - The high-strength temporary plugging agent has high plugging rate of more than 96%, and high blocking removal rate of more than 81%, less residual gel blocking, little impact on the formation, and high plugging strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for high-strength temporary plugging agent capable of realizing well zone seepage, prepared by the above method.
