A copolymer, a preparation method therefor, and a use thereof. The copolymer contains an olefin backbone, and a sulfonic acid group, an acylamino group, an aminoacyl group, and a tertiary carbonate group, which are bonded to the olefin backbone. By means of a synergistic effect of these functional groups, the hydrolysis rates of the acylamino group and the aminoacyl group can be controlled, and precipitation is inhibited, thereby finally achieving a high hydrolysis rate. The copolymer can be used for profile control and flooding of a high-temperature high-salinity oil reservoir, especially a carbonate rock oil reservoir. The copolymer can be slowly hydrolyzed to release cross-linking sites in the oil reservoir environment, and the cross-linking sites released by hydrolysis can bind with a cross-linking agent to form a profile control and flooding system. After injection into the oil reservoir, initial low viscosity is achieved, and during migration, cross-linking groups are continuously released by means of slow hydrolysis, thereby achieving stepwise tackifying; in addition, the profile control and flooding system maintains certain viscosity and strength, so that deep profile control and flooding, flow channel adjustment, and long-lasting plugging are achieved.
