Sandstone reservoir flooding rate map generation method and device, medium and equipment

The invention relates to the field of sandstone reservoir development, and discloses a sandstone reservoir flooding rate map generation method and device, a medium and equipment. According to the method, the M modeling wells can be determined from the N production wells according to the well layering coordinates of the oil-bearing stratum of the sandstone reservoir area in the N production wells, and M is larger than 1 and smaller than N. Determining the oil-water interface position of the oil-bearing stratum in each modeling well and the flooding duration of each modeling well, and determining the flooding rate of each modeling well based on the oil-water interface position of the oil-bearing stratum in each modeling well and the flooding duration of each modeling well, and generating a flooding rate map of the sandstone reservoir area according to the flooding rate of each modeling well. According to the method, the flooding rates of the different position areas in the sandstone reservoir area can be determ
