EXPERIMENTAL SETUP FOR PHYSICAL MODELING OF THE PROCESS OF OIL DISPLACEMENT FROM HOMOGENEOUS RESERVOIRS OF VARIOUS PERMEABILITIES USING SUPERCRITICAL CARBON DIOXIDE AND WATER RIMS
A.V. RADAEV, A.N. SABIRZYANOV, A.A. MUHAMADIEV

An experimental setup has been created to study the process of oil displacement by supercritical CO2 and rims of supercritical CO2 and water from a model of a homogeneous reservoir of various degrees of water cut. At the experimental setup, the process of multicomponent filtration of oil-water-supercritical CO2 systems was studied on the isotherm 333 K in the pressure range up to 14 MPa. Trial experiments were carried out at various degrees of watering of the reservoir model. New data have been obtained on the coefficient of oil displacement by rims of supercritical CO2 and water from a homogeneous porous medium. The results showed that the use of supercritical CO2 in the fi ltration processes of multicomponent reservoir systems allows for the additional displacement of high viscosity oil, and the value of residual oil saturation decreases.
Keywords: Supercritical fluid, experimental setup, rim of supercritical CO2 and water, oil displacement coeffi cient, residual water and oil saturation.
