METHOD OF CREATING MICRO-MODEL OF PORE SPACE BASED ON COMPUTED TOMOGRAPHY OF CORE Russian patent published in 2024 - IPC G01N23/46 

FIELD: physics.

SUBSTANCE: use for creation of micro-model of pore space based on computed tomography of core. Essence of the invention consists in the fact that based on the results of direct hydrodynamic modelling of a single-phase flow of a linearly viscous liquid in the reconstructed pore space of the core, obtained by computed tomography, calculating density function of current line sinuosity and permeability, creating a certain number of packages of winding channels of a given shape and section based on the analytical solution of the Navier-Stokes equations for rectangular cross-section channels and Darcy's law, for the hydrodynamic connection between the packages of the winding channels, a system of buffer zones is formed, for uniform supply of displacement fluid, a system of supply channels is formed in the form of a binary tree, and a drainage zone is formed for removal of the displaced and displacing fluids.

EFFECT: providing the possibility of creating a micro-model of pore space, having filtration-capacitance characteristics of a real sample of porous rock.
