摘　　要：天然气管道干燥是输气管道建设投产中的重要步骤，会影响后期管道的输气品质与安全。介绍了几种管道干燥方法，重点介绍了干空气干燥法的基本原理、工艺要求及其优点，分析了影响干空气干燥的各种因素，结合江苏LNG接收站干燥工艺，说明了江苏LNG接收站工艺管道的吹扫方法，另外介绍了两种实际上采用的吹扫方式，分析其利弊，最后总结了吹扫过程中遇到的问题及解决办法，提出了一些改进意见。（图3，表2，参6）Natural gas pipeline drying is an important step in the construction of gas pipelines, which influences the quality and safety of the gas pipelines. This paper introduces several pipeline drying methods, and mainly introduces the rationale, the technological requirements and the advantages of dry air exsiccation method, and analyzes various kinds of factors that affect dry air exsiccation. Combined with the drying process of Jiangsu LNG terminal, illustrates the purging method of the process pipelines at Jiangsu LNG receiving terminal. Introduces two methods used in practice and analyses the advantages and disadvantages. Finally summarizes the problems encountered in the process of purging and relevant solutions, and puts forward some improvement suggestions. （3 Figures, 2 Tables, 6 References）.
