用涡轮流量计测量多相流流量

Flow Rate Measurement in Multiphase Flow Using Turbine Flow-meter

对涡轮流量传感器进行了理论分析,给出了涡轮流量计仪表常数的计算方法,讨论了获得较大固有仪表常数K0时涡轮传感器结构参数(如叶片数、涡轮半径、口径等)的优化组合问题,通过多相流动实验,总结出K0与流动密度之间的实验关系,由此给出用涡轮流量计测量多相流的半理论半经验公式,并在油井多相流量测量中得到了实际应用,符合较好。

Turbine flow-meter factor K is deduced by theoretical analysis of turbine transducer firstly. Secondly, discussed how to make a maximum K by arranging transducer parameters. Thirdly, carried out an empirical relationship between K and flow density based on multiphase flow experiment. Finally, presented a semi-physical and statistical expression used for measuring or estimating multiphase flow rate.
