摘　　要：基于国内外油水流乳化及转相、黏度测定与摩阻预测的研究现状,探讨了油水流动摩阻预测误差的产生根源和解决对策。油水流动的乳化程度及转相条件、油水流型变化规律、油水黏度测定等因素均将影响油水流动摩阻计算的准确性,其根源在于油水混合液在旋转流变仪、环道模拟装置等测试分析系统与实际管道中的流动特征及组成性质截然不同。为此,以建立测试系统与实际管道中油水流动规律的内在联系为切入点,提出相应的研究思路,以期为稠油掺水流动摩阻预测的深入系统研究提供参考。(参40)Based on the research status of oil-water emulsion and phase inversion, viscosity measurement and friction prediction at home and abroad, this paper analyzes the causes of error in oil and water flow friction prediction and countermeasures. Factors affecting the accuracy of oil and water flow friction calculation are levels of oil and water emulsion, phase inversion conditions, variation of oil-water flow type and oil-water viscosity measurement, the root causes are the quite different flow characteristics and composition ofoil and water mixture in real pipeline and rotational rheometer or loop simulation test apparatus. For this reason, the paper proposes a research approach proceeding from the establishment of intrinsic link between oil and water flow pattern in test system and real pipeline, in the hope to provide a reference to the in-depth and systematic research in flow friction prediction on heavy oil and water mixture. （40 References）
