摘要/Abstract

摘要： 为了研究温度、含水率对惠州油田原油表观黏度的影响，利用MCR302型高温高压流变仪对含水原油的流变性进行了测试。实验表明，当含水率一定时，表观黏度与温度成指数规律分布；温度一定时原油的表观黏度与含水率成三次多项式分布。结合量纲分析，给出了表观黏度与温度、含水率的综合关系式。拟合了综合关系式中的系数，绘制了表观黏度与温度、含水率的三维曲面图，并分析了数据拟合的精度。研究认为，该综合关系式从本质上反映了温度、含水率对表观黏度的影响，对高含水原油在集输过程中压降的计算具有重要的指导意义。

Abstract: To study the effects of temperature and water content on the apparent viscosity of crude oil in the Huizhou oilfield, the rheological characteristics of wet crude oil were tested using a MCR302 high-temperature and high-pressure rheometer. The experimental results revealed an exponential relationship between the apparent viscosity and temperature with constant water content in wet crude oil. With a fixed temperature, the apparent viscosity and water content were found to follow a cubic polynomial distribution. By combining these findings with dimensional analysis, we proposed a comprehensive correlation describing the relationships among the apparent viscosity, temperature, and water content. The coefficients of the correlations were obtained by fitting the experimental data with the proposed expression. A three-dimensional surface map was plotted to show the change in the apparent viscosity with different temperature and water-content conditions. The accuracy of the empirical fitting was also analyzed in this study. As demonstrated in this study, the comprehensive correlation fundamentally reflects the effect of temperature and water content on the apparent viscosity of wet crude oil. This correlation can provide valuable guidance in calculating pressure drop during the collection and transportation of high water-content crude oil.

Key words: wet crude oil, apparent viscosity, rheology, comprehensive correlation, phase reverse point
