Abstract
A rock brittleness analysis method and system based on mineral content and distribution, and a device are provided. The rock brittleness analysis method includes: performing digital processing on an image of a rock, and performing an autocorrelation analysis on a two-dimensional (2D) array obtained after the digital processing to obtain an autocorrelation coefficient variation curve; using an abscissa value corresponding to an ordinate value of dropping to 1/e on the autocorrelation coefficient variation curve to be an autocorrelation length of the rock; constructing an autocorrelation function for describing a mineral distribution according to the autocorrelation length and the distribution characteristics of a mineral and an elastic modulus in the rock; reconstructing a rock sample of the rock to obtain density and elastic modulus distributions of the rock; and partitioning meshes of the reconstructed rock sample to obtain a brittleness index distribution of the to-be-analyzed rock partitioned in different scales.
