The mathematical model of process of a non-stationary two-phase two-component filtration of system oil - supercritical CO
in homogeneous porous environment is developed. Results of numerical researches of a problem of a non-stationary two-component two-phase filtration of system oil - supercritical CO
are given in layer in the course of replacement of model oil by supercritical CO
from homogeneous porous environment. Results of numerical modeling showed that a rejection of settlement data from experimental in case of oil replacement by water below, than at replacement of its supercritical CO
. The deviation of numerical results from the experimental doesn't exceed 13%.
