Measurement of Proppant Geometrical Characteristics Based on Chain Code

Abstract:

In order to evaluate geometrical characteristics of proppant scientifically and accurately, both of the theoretical analysis and the experimental method were adopted. By binaryzation processing of the particles digital image, using chain code technology to realize regional boundary calibration to obtain vertex chain code and coordinates of boundary point, an algorithm has been inferred for particle size, sphericity and roundness, and problem-solving process for geometrical characteristics has been confirmed by experiments. The results indicate that measurement of geometrical characteristics, algorithm and analysis for the sizing and averaging have become rationale for the particle pattern recognition and analysis system. The conclusion breaks through traditional sieving methods in measuring and contrast plate method, laying foundation for the application of computer image analysis technology.
