摘要
介绍了目前国内外天然气管道常用的干燥方法。从天然气管道投产作业方案及现场准备、干燥、置换和升压四个方面阐述了长输天然气管道投产技术与注意事项。分析了影响干燥时间的主要因素,给出了干燥时间、燃气置换所需流量和累积气量的估算方法。
The paper introduces common dewatering methods of long-distance gas transmission pipelines at home ano abroad.Commissioning technology and requirements of gas pipeline are described from four aspects of implement program/field preparation.dewatering,gas displacement and pressure boosting.Primary factors influencing on drying time are analyzed.Estimation method for drying period,flowrate and gas volume accumulation needed in gas displacement are given.
