Abstract

The paper represents the results of filtration studies on fresh water injection into a reservoir model under conditions of low temperatures. The experiments were carried out on the core material of a dolomite-type carbonate bed of the Eastern Siberia field with the simulation of reservoir conditions. It was found that the water permeability of the reservoir model at residual oil saturation decreases significantly with a decrease in temperature from 20 to 5 °C. The performed set of laboratory studies showed that the results obtained are mainly induced by the deposition of heavy oil components in the pore space and the possible formation of stable low-mobile water-oil mixtures that impede the movement of water, which in practice is accompanied by a decrease in the intake capacity of injection wells.

Key words:

dolomites, asphalt-resin-paraffin components, phase permeability, filtration, organic solvent, bottomhole formation zone, waterflooding, phase equilibrium, saturation pressure, clogging of pore space
