The invention provides polymer microspheres for high temperature hypersalinity reservoir deep profile control and a preparation method thereof. In the method, based on the method that photopolymerization is used to prepare the polymer microspheres, heat and salt resistance polymer materials such as sodium 3-acryloylamino-3-methyl butyrate, 2-acryloylamino-2-methylpropane sulfonic acid, acrylamide monomer and the like and water-soluble anionic monomer are adopted and dispersant and cross-linking agent are added as so to form oil-water mixed emulsion in the mixed medium of surfactant and solvent; then initiator is decomposed by ultraviolet through photopolymerization under controllable temperature so as to initiate emulsion polymerization and 50-500nm of microspheres are formed. The invention utilizes the ability of microspheres that microspheres can be dispersed in arbitrary concentration and injected in the water and can gradually swell after entering in depth of the formation to plug the ...
