长庆油田天然气流量计量实流校准、比对系统

Real Flowrate Calibration and Comparison System of Natural Gas Flow Measurement in Changqing Oilfield

天然气流量测量的精度受多方面因素影响,因此必须建立统一的检定流量测量仪表准确度的方法,实流检定技术是流量测量仪表准确度检定的最新发展。文章阐述了长庆油田在役的移动式在线天然气实流检定装置的标准表选型、检定流程及特点、技术指标、基本配置、现场检定以及固定式在线天然气实流校准系统的检定设计流程、基本配置等情况。

Because the precision of natural gas flow measuring is affected by many factors, a kind of unitive calibrating method for flowmeter precision needs to be established, and the real flowrate calibrating technique is the newest development in such aspect. This paper describes standard meter selection, calibration process, technical specifications and basic configuration of the mobile online natural gas real flowrate calibration device being served in Changqing Oilfield, as well as the calibration design process, basic configuration and field calibration of the fixed type online natural gas real flowrate calibration system.
