Fracturing effect judgment method and device

The invention discloses a fracturing effect judgment method and device. The method comprises the following steps: determining the relationship between the proppant erosion amount and the perforation hole erosion area; the erosion area of the single underground erosion hole is obtained, and the sand inlet amount of the single underground erosion hole is determined according to the area in combination with the determined relation between the area and the erosion area; according to the sand feeding amount of a single hole, the sand adding uniformity index between the clusters in the fracturing sections of the horizontal well is determined; according to the sand adding uniformity index of each fracturing section, the fracturing effect of each fracturing section of the horizontal well is judged. By means of the mode, quantitative judgment on the sand feeding conditions of different positions, different directions and even centimeter-level perforation holes of perforation clusters is achieved, accurate judgment on
