| 摘 要： | 为了得到油田现场中高含水后期原油水两相流动规律,选取长庆某典型高含水原油,测量其基本物性及反相点,改进了适合易乳化原油的反相预测模型,对比了不同温度下表观黏度反相前后的差异。结合油水两相管流环道实验,得到了不同含水率下压降与流量的关系,分析了压降预测结果和实验结果的误差。结果表明,该原油在低于凝点(26.0℃)且水为连续相时表现出较强的剪切稀释性,高于凝点时,反相前温度对体系黏度的影响起主导作用,而在反相后温度对体系黏度的影响不大。改进反相预测模型能较好地预测高含水原油的反相点。反相前,压降随着含水率的升高而增大,反相后压降出现骤降。高含水原油的基本物性与流动规律的研究为油田的安全高效生产提供了一定的理论指导。
