摘要
阐述了阻抗式含水率计原理,给出了其油水两相漂流模型,应用该模型处理了阻抗式含水率计测量的数据,通过拟合获取参数.实验结果表明,测量含水率的最大绝对误差为16.7%,而采用漂流模型校正后的最大绝对误差为7.57%,模型校正后的含水率预测值精度较高.
The paper expatiates the principle of impedance water-cut sensor and presents the drift-model of oil/water phase.The measured data from the sensor was transacted using this model and the key parameters were obtained.The dynamic experimental result demonstrates that the maximal error of water-cut measurement is 16.7%,but the emendation error used by the model is 7.57%.
