天然气长输管道输差的分析与控制措施

Analysis and control measures of transmission difference of long-distance natural gas pipeline

对于长输管道运营管理公司而言,如果输差没有很好地分析和管控,将很可能导致管网气量日益亏损,影响公司效益。输差控制作为日常生产运营管理的重要工作,其控制水平也直接反映管道的运行状态及运营管理水平。首先介绍了输差概念及计算方式,然后对天然气长输管道中输差产生的原因进行分析,最后提出可行的控制措施。希望为解决天然气管网输差问题提供参考。

For long-distance pipeline operation management companies,the transmission difference control level directly reflects the operation state and operation management level of the pipeline.If the transmission difference is not well analyzed and controlled,it is likely to lead to the increasing loss of gas and affect the company's benefits.This paper first introduces the concept and calculation method of transmission difference,then analyzes its causes,and finally puts forward feasible control measures,hoping to provide reference for solving the problem of transmission difference in natural gas pipeline network.
