Compressed proppant breakage rate calculation method based on image processing

The invention discloses a method for calculating the breakage rate of a pressed proppant based on image processing, and the method comprises the steps: applying a loading pressure to the proppant, and obtaining the pressed proppant; the proppant is uniformly laid on a plane, and image information of the proppant is obtained; processing the image information, counting the area distribution of the proppant particles in the image information, and obtaining the radius distribution condition of the proppant particles according to the area distribution information of the proppant particles; and drawing a grading curve chart of the normalized mass fraction and the normalized radius of the propping agent particles, and obtaining the breakage rate of the propping agent through the grading curve chart. According to the method for calculating the crushing rate of the pressed proppant based on image processing, the crushing rate of the proppant can be rapidly and conveniently obtained, and a new way is provided for obtai
