EFFICIENT METHOD OF SELECTING A REPRESENTATIVE ELEMENTARY VOLUME ON DIGITAL REPRESENTATIONS OF POROUS MEDIA

摘要

FIELD: test equipment.;SUBSTANCE: invention consists in obtaining segmented volume which characterises the pore space and at least one solid phase; outputting average value of P1 property of the first target function P1 for the entire segmented volume; calculating the mean-square deviation σ_VOL relative to the average value of P1 property for the entire segmented volume; determining a plurality of sub-volumes in volume; calculating the mean-square deviation σi value P of the first target function P1 property relative to the average value of P1 property for each of the abovementioned sub-volumes; defining all representative sub-volumes-candidates for which the mean-square deviation σi satisfactorily corresponds to σ_VOL; selecting and storing representative sub-volume from the candidates; and using the representative sub-volume to obtain at least one desired value of property.;EFFECT: possibility to increase validity of estimation of representative digital volume of sub-model corresponding to the model of porous media.;21 cl, 92 dwg
