| titleOfInvention | High-molecular profile control and plugging agent, and preparation method and application thereof |
| abstract | The invention discloses a high-molecular plugging agent and a preparation method and application thereof, belonging to the technical field of oil exploitation. The high-molecular profile control agent comprises an oil phase and a water phase, wherein the oil phase comprises white oil and a composite emulsifier; the water phase comprises acrylamide, acrylic acid, dimethyl allyl ammonium chloride, 2-acrylamide-2-methyl propanesulfonic acid, N-methylene bisacrylamide, an initiator and water. The high-molecular plugging agent provided by the embodiment of the invention is prepared by taking white oil as a dispersion medium, acrylamide, acrylic acid, a cationic monomer, namely dimethyl allyl ammonium chloride, and an anionic monomer, namely 2-acrylamide-2-methylpropanesulfonic acid, as a polymer monomer, and N, N-methylene bisacrylamide as a cross-linking agent through a reverse microemulsion polymerization method under the initiation action of ammonium persulfate-ammonium bisulfite in a redox system, and has the advantages of low preparation cost, excellent high temperature resistance, high pressure resistance and good plugging effect. |
