An experimental setup for studying the displacement of oil in a wide range of pressures (up to 20 MPa) and temperatures (up to 373 K), that reflects thermobaric, geological, and physico-chemical conditions in real oil-beds and parameters of displacing agents is constructed. The results of experimental displacement of kerosene by supercritical carbon dioxide at 313 ÷ 353 K and 7 ÷ 12 MPa demonstrate a high efficiency of this technology for the output of low-viscosity oils.
