中文摘要：

针对采用单一传感器无法对油水两相流流量准确测量的问题，将电导环阵列和内锥式差压2种传感器相结合，采用卡尔曼集中式融合估计方法与并行式融合估计方法分别实现油水总流量的测量。前者是根据局部各个传感器的测量值来重构全局的油水两相流总流量，后者是根据局部各个传感器测量值的估计值来重构全局的油水两相流总流量。实验测试结果表明，这2种方法均可以实现油水总流量的较准确测量，且并行式融合结果优于集中式融合结果。

英文摘要：

To overcome the disadvantages of inaccurate measurement on oil-water two-phase flow process parameters utilizing a single sensor,a measurement system combining the conductive ring sensors array and the inner cone dif-ferent pressure sensor was proposed. Kalman centralized fusion estimation and Kalman parallel fusion estimation were studied respectively to estimate the total flow rate of oil-water two-phase flow. The global estimation of the total oil-water two-phase flow based on Kalman centralized fusion was reconstructed by the local observations of each sensor. The global estimation of the total oil-water two-phase flow based on Kalman parallel fusion was reconstructed by the local estimations of each sensor. Dynamic results show that both the two methods can achieve an accurate measure-ment of the total flow rate of oil-water two-phase flow,and the Kalman parallel fusion estimation result is superior to the Kalman centralized fusion estimation result.
