【摘要】 利用涡轮流量计测量了油水两相流动时的混合流量,重点研究了油相黏度变化和流量计入口油水相含率变化对测量精度的影响。实验采用了七种不同的油相黏度(50,160,225, 400,700,1100,1450 MPa·s),并在含油率0～100%范围内记录了292组不同油水混合流量下的测量值。研究结果表明,当油相黏度为低黏值50 MPa·s和160 MPa·s时,涡轮流量计的测量误差较小,且不受入口油相含率的影响,绝对误差均在±5%以内。当油相黏度大于225 MPa·s时,随着入口油相含率的增加,误差逐渐增大。当油相黏度进一步提高到1100 MPa·s以上时,涡轮流量计在较低的入口油相含率下进入非线性失效区。更多还原

【Abstract】 The mixture flow-rates measurement of oil-water two-phase flow was investigated by a turbine flow-meter in this paper.The research target is the Influences of viscosity variations and oil fraction of oil-water two-phase flow to Turbine Flow-Meter.The experiment was finished in seven different oil viscosities and 292 measured values were recorded under the oil fraction from 0 to 100%.It is shown that,when oil viscosity is 50 and 160mPa·s,measured errors are not affected by input oil fraction and relative error is within±5%.But when oil viscosity reaches to 225mPa·s, absolute errors turn into negative values from positive values and take on rapidly decreasing trend along with the increases of oil input fraction.When oil viscosity further increases to 1100mPa.s,the turbine flow-meter turns into nonlinear work area.更多还原
