| description | The invention provides a viscous polymer solution for well wall strengthening, a well wall strengthening agent and a preparation method, the method comprises the following steps: dissolving polymeric alcohol in hot water to obtain a polymeric alcohol solution, and the hot water comprises deionized water or distilled water with the temperature of 70-90 DEG C; mixing a nonionic monomer, a cationic monomer, an anionic monomer and a polymeric alcohol solution, and carrying out esterification dehydration reaction to obtain a viscous polymer solution; adjusting the pH value of the viscous polymer solution to 7-8, and then drying and grinding to obtain the well wall reinforcer; wherein the molar ratio of the polymeric alcohol to the nonionic monomer to the cationic monomer to the anionic monomer is (0.04-1.00): (50-80): (4-9): (10-13). The well wall reinforcer comprises the reinforcer prepared by the method for preparing the well wall reinforcer. The method has the beneficial effects that the rock cohesion is improv |
