摘要： 油水两相流的流动机理十分复杂, 存在着“ 乳化” 、 “ 反相” 等特有现象, 其流量测量有很大难度。差压 法作为一种应用广泛的流量测量方法, 从原理上来看适用于油水两相流的流量测量, 但相关研究较少。采用文丘里 管作为节流装置, 实现了油水两相流流量的差压测量。实验中以均相流模型为基础, 以混合前测量的油水流量作为 参考值, 验证了文丘里管的差压值分别与质量流量计输出的体积流量值和混合密度值组合测量的效果。实验结果 表明, 油水总质量流量的测量精度较高, 文丘里管与混合密度组合时精度尚可, 与体积流量组合时达不到测量要求。

Abstract: The flow mechanism of the oilwater two phase flow is very complicated. Some specific phenomenon such as "emulsification" and "inversion" exists in it making it hard to measure the flow. Differential pressure method, which is a widely used flow measurement method, can be applied to the oilwater two phase flow theoretically. However, there are little correlation studies. Using the Venturi tube as the throttle device,the differential pressure of the oilwater two phase flow rate is measured. Based on the homogeneous flow model, the effects of the differential pressure of the Venturi tube combines respectively with the volume flow and the mixture density are verified, taking the oil and water flows without mixing as the reference value. The experimental results show that the accuracy of the oilwater mixture mass flow measurement is relatively high, and the accuracy of the combination of the Venturi tube with the mixture density can be accepted, while the combination with the volume flow cannot reach the measurement requirements.
