METHOD OF INVESTIGATION OF FILTRATION-CAPACITIVE PROPERTIES OF MINERAL ROCKS Russian patent published in 2017 - IPC G01N23/83 

FIELD: mining.

SUBSTANCE: select the core samples in a wide range of filtration and capacitance properties, scan the X-ray microtomograph of the selected samples to obtain three-dimensional images of the samples that segment into the pore space and the rock skeleton, extract several segments from the segmented images, determine the porosity value for each fragment (m0), increase the porosity of the fragment by the pixel extension of the pore space and determine its value (m1), with the aid of r (k1) of the fragment, the values of the porosity and permeability for all fragments isolated from each sample are determined, their trends are plotted, along the trend lines, the permeability values of the initial fragments (k0) corresponding to the values (m0) are determined and, according to the established values of porosity and permeability for the initial fragments, their correlation relation is found.

EFFECT: reduction of the lower limit for calculating the permeability of rocks.
