温度对乳化稠油含水率反相点及增黏倍数的影响

以胜利油田2种普通稠油和3种超稠油为研究对象, 考察了5种稠油含水率反相点和增黏倍数随温 度的变化规律。结果表明, 随着温度的升高稠油的含水率反相点增大; 3 0%含水率的乳状液其增黏倍数先增大后减 小; 反相点时乳状液的增黏倍数逐渐增大。比较相同温度下5种稠油的含水率反相点以及增黏倍数发现, 稠油净化 油的黏度越小, 乳化越容易进行, 含水率反相点越高, 3 0%含水率乳状液的增黏倍数越小, 反相点时乳状液的增黏倍 数越大。

The Effect of Temperature on Moisture Inverted Point and Viscous Ultiples

Two ordinary heavy oils and three super heavy oils in shengli oil field are used to study and the effect of temperature and viscosity on the moisture inverted point and the viscous multiples. The results show that the inverted point increases with increasing of the temperature, and the viscous multiples of the inverted point also increases. While the viscous multiples of the same moisture content firstincreases and then decreases. Comparing the inverted point and viscous multiples, it is found that the one which has low viscosity will have high inverted point, low viscous multiples of the same moisture content and high viscous multiples of the inverted point.
