摘要： 综合涡轮流量计的计量原理、山西省非常规天然气井口气的气质和流动特性，分析了流体组分和脉动流对涡
轮流量计计量准确度的影响。结果表明，实际组分和流动特性均会使涡轮流量计产生正向系统误差。基于此对修正正供
销差提出了建议。在山西省非常规天然气大力发展之际，面对绝大多数企业贸易结算仍采取涡轮流量计计量的实际现
状，该探究结果对上、中、下游的供销差管理具有一定的实际指导意义。

Abstract: Based on the measurement principle of turbine flowmeter, the quality and flow characteristics of unconventional natural
gas wellhead gas in Shanxi Province, this paper analyzed the influence of fluid composition and pulsating flow on the measurement
accuracy of turbine flowmeter. The results show that the actual composition and flow characteristics will cause the turbine flowmeter
to produce positive system errors. Based on this, suggestions were made for correcting the positive supply and sales difference.
With the vigorous development of unconventional natural gas in Shanxi Province, in the face of the actual situation that most companies
still adopt turbine flowmeters for trade settlement, the results of this inquiry have certain practical guiding significance for
the management of positive supply and sales difference upstream, middle and downstream.

Key words: flowmeter; accuracy; gas composition; pulsating flow; positive supply and sales difference
