摘要

The problems of numerical and experimental modeling of cyclic carbon dioxide injection in a supercritical state for low-permeability reservoirs were considered in this study. Sensitivity analysis of the cumulative oil production from a number of physical - chemical parameters of the reservoir was performed. The experimental and numerical simulation of cyclic injection of carbon dioxide (huff-n-puff) on core samples of low permeability reservoirs was carried out. Calculations of phase equilibrium pumping supercritical fluid were conducted. Two-dimensional model was proposed for huff-n-puff technology of cyclic injection of CO2, which is a periodic pumping in and pumping out of the solvent into the formation.
