温度对稠油/热水相对渗透率的影响
Impact of Temperature on Relative Permeability of Heavy Oil/Hot Water
摘要
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.关键词
