Key words: supercritical fluid, oil extraction coefficient, thermobaric conditions
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.
