摘要/Abstract

摘要： 以辽河油田杜229+84 超稠油区块的油样为实验对象,研究了超稠油的原油密度、粘度、混合原油乳状液密度、粘度、乳状液膜压及混合原油脱水水滴沉降速度等与温度的变化关系;分析了温度对超稠油脱水速度的影响。实验结果表明,温度升高,混合原油及其乳状液的密度、粘度均减小,原油与脱出水密度差先增加后减小,水滴在介质(原油)中沉降速度增加,稠油乳状液膜压降低,升高温度有利于加快超稠油的脱水速度;油水密度差在70~95℃增加幅度最大,原油及其乳状液粘度的减小幅度最大。综合考虑经济因素,超稠油最佳破乳脱水温度为80~95℃。

Abstract: Taking oil sample from DU229+84 super-heavy oil block in Liaohe oil field as the experimental object, this paper studies the relationship of super-heavy oil density and viscosity, mixed crude emulsion density and viscosity, emulsion interfacial film pressure and mixed crude dehydrated droplet fall velocity etc. vs. temperature, and analyzes the effect of temperature on the rate of super-heavy oil dehydration. Experimental results show that the density and viscosity of mixed crude oil and emulsion decrease; the density difference between crude and dehydrated water increases followed by decreasing; the droplet fall velocity in medium (crude oil) increases and the interfacial film pressure decreases with increasing of the temperature. The temperature increase is favorable to speed up the rate of superheavy oil dehydration. At the temperature of 70~95℃, the density difference goes to the highest, and the viscosity reduction of the crude oil and emulsion achieves the maximum. Taking economic factors into comprehensive consideration, the best temperature of super-heavy oil breaking dehydration is 80~95℃.

Key words: super-heavy oil dehydration, emulsion, density, viscosity, temperature
