Experimental Stand and Methodology for Conducting Experiment to Measure the Solubility Coefficient of Supercritical Carbon Dioxide in Hydrocarbons in a Homogeneous Porous Medium

Abstract

The article presents the results of studies of the process of oil displacement with supercritical CO₂ fringes and water from a low-permeable heterogeneous oil reservoir with a water content of 8% at a pressure of 8 and 12 MPa. The results show that an increase in the CO₂ injection pressure does not lead to an increase in the oil displacement coefficient within the experimental error. The mechanism of the process of displacing oil from a low-permeable heterogeneous reservoir is considered. The results of the experiment are processed in the form of a generalizing dependence.
