The present invention provides a high-strength temporary plugging agent capable of realizing well zone seepage and a preparation method thereof. In parts by weight, it is prepared by the following method: taking hydrophilic nanomaterials and uniformly dispersing them in a solvent, and then adding glycerol allyl ether monomer, after stirring or sonicating for 0.5-3h, add acrylamide monomers, stir to dissolve them, and add N,N-methylene acrylamide, acrylate compounds and The initiator continued to react for 5-12h, and after the reaction was completed, it was dried. The high-strength temporary plugging agent capable of realizing well zone seepage of the present invention has a relatively high plugging rate, which can reach over 96%; With less glue, it has less impact on the formation, and at the same time, its plugging strength is high, and the scope of application is wider, and it can be used for seepage volume fracturing in the well zone. |
