摘要
中乌天然气管道涉及多国跨境贸易计量交接,为了提高跨国贸易交接计量仪表精度,延长检定周期。在乌兹别克斯坦首、末站安装了超声波流量计远程诊断(CBM)系统。通过CBM系统的软硬件完成超声波流量计的远程声速核查,以及增益和信号质量等相关参数的指标确认,实现了预定目标,减少了大量因重复安装调试维护所投入的维护费用,降低了输气生产时间成本,为输气生产中的工艺、计量等故障分析提供了依据,提高了计量管理的工作水平,为跨国长距离天然气输气管道计量管理工作积累了宝贵经验。
China-Uzbekistan Gas Pipeline involves in multinational cross-border metering. In order to improve the accuracy and service life of the meters, a remote diagnosis system （CBM） of ultrasonic flowmeter is installed at the initial and terminal stations in Uzbekistan. With the CBM hardware and software, the remote sonic velocity of the ultrasonic flowmeter is verified, and the gain, signal quality and other parameters are confirmed. In this way, the intended target is realized. Meanwhile, the maintenance cost for repeated installation and maintenance and the time cost of gas production are reduced. The practice provides a reference to the fault analysis of process and metering during gas transportation. Accordingly, the metering management is improved and valuable lessons are learnt for metering management of cross-border long-distance naatral gas pipelines.
