An experimental setup was created to study the process of oil displacement by supercritical CO2 and fringes of supercritical CO2 and water from the model of homogeneous and inhomogeneous formation of different degrees of water saturation. The process of multicomponent filtration of oil-water-supercritical CO2 systems at 333 K isotherm in the pressure range of up to 14 MPa was studied at the experimental plant. The new data, the oil displacement efficiency of supercritical CO2 from a homogeneous porous medium with water content of 65% and rims supercritical CO2, and water from homogeneous porous medium with a water cut of 25%. The results showed that the use of supercritical CO2 in the filtration processes of multicomponent reservoir systems allows further displacement of oil from the watered porous medium.
