摘　　要：在天然气贸易交接计量过程中,为确保贸易双方的经济利益,要求流量计量仪表应具有精确度高、能耗低和维修少的优良特性。长庆气田在给“西气东输”管道供气的天然气贸易计量系统中,首次采用了气体超声流量计,取得了一定的工程设计经验和较好的现场应用效果。In custody transfer of natural gas, for insuring the economy profits of both parties in trading, it is required that flow measuring instruments should have offered excellent characteristics of high accuracy, low energy consumption and ease maintenance. For this purpose, gas ultrasonic flowmeters are firstly adopted in custody transfer system of CHANGQING Natural Gas Field that is part of ＂West-East Natural Gas Transportation Project＂. Certain experience of engineering design and better field apphcation effects are accomplished.
