Impact of Temperature on Relative Permeability of Heavy Oil/Hot Water

Abstract

Abstract: There is limited research on the oil-water relative permeability of thermally recovered heavy crude oil reservoirs, and the oil-water movement rules have not been clarified. Thus, this experimental study focuses on the relative permeability of heavy oil/hot water at different temperatures (100~280℃); explores the rules concerning the impact of end-point saturation of the relative permeability curve and the corresponding single-phase permeability of heavy oil/hot water; and analyses the mechanism of the variation law from a microscopic perspective. Experimental results suggest that the bound water saturation increased initially and then decreased as the temperature rose; the oil-phase permeability gradually declined under the bound water condition; and the residual oil saturation was observed to decrease, whereas the corresponding water-phase relative permeability gradually increased. The water-phase permeability was lower under the residual oil condition with different temperatures. Studies on the variation laws of relative permeability of heavy oil/hot water at various temperatures will deepen the understanding of fluid flow characteristics of thermal recovery reservoirs.

Key words: temperature, heavy oil, hot water flooding, relative permeability, seepage characteristic
