【摘要】：液体超声波流量计(简称液超)在大口径管道计量中有突出的优势,但实流标定方法复杂是其用于外输计量的瓶颈。南海某油田在国内首次将液超应用于浮式生产储卸油装置(FPSO)贸易交接计量。通过分析液超测量原理及检测特性,对其标定方案进行设计,在国内首次尝试采用体积管直接标定液超。通过对比分析体积管与标准表标定结果,得出结论——增大体积管体积及采用多次连续标定结果进行评价可有效解决体积管直接标定液超问题。对液超在海上平台的后续应用有重要意义。
[Abstract]:Liquid ultrasonic Flowmeter (referred to as liquid Supermeter) has outstanding advantages in large diameter pipeline metering, but the complex method of real flow calibration is the bottleneck of its application in external metering. It is the first time in China that a South China Sea oil field applies liquid excess to trade measurement of floating production storage and unloading unit FPSO. Based on the analysis of the principle and characteristics of liquid overmeasurement, the calibration scheme is designed, and the volume tube is used to calibrate the liquid excess directly in China for the first time. By comparing and analyzing the calibration results of volume tube and standard table, it is concluded that increasing the volume of volume tube and evaluating it with multiple successive calibration results can effectively solve the problem of direct calibration liquid excess of volume tube. It is of great significance for the application of liquid super in offshore platform.
