FIELD: measurement equipment.
SUBSTANCE: invention relates to methods of description of characteristics of 2D and 3D samples to determine spread of pore body and pore channel sizes, and also curves of dependence of capillary pressure in a porous medium. Input information includes petrographic images of high resolution and laboratory measurements of porosity. Output information includes distribution of pore body and pore channel sizes and modelling of curves of capillary pressure dependence both for the pore body and pore channels.
EFFECT: improved analysis.
