The invention discloses a profile control agent slug parameter optimization method suitable for oil reservoir water shutoff, and belongs to the technical field of oil and gas exploitation. A channeling channel is determined, and profile control agent slug parameters are optimized with the target residual resistance coefficient after plugging, the plugging volume, the plugging position and the slug number of the profile control agent in the channeling channel as variables in sequence and with accumulated oil production and the like after regulation and control as optimization targets. According to the method, the residual resistance coefficient, the plugging volume, the plugging position and the slug number after plugging can be quantitatively optimized, and according to the result given by the research, the follow-up implementation scheme can be used for determining the residual resistance coefficient of the oil reservoir according to the temperature, the pressure and the mineralization degree of the target o
