China has a vast territory,a wide range of mountains and rivers,and complex terrain.In recent years,there are many construction projects for oil and gas pipelines,especially for large-diameter pipelines crossing mountain areas.The key to mountain pipeline construction is how to pipe,Pipeline technology,is to solve the mountain construction of the biggest difficulties for the smooth construction of the project will play a significant role.Taking the mountainous section of Sichuan-to-East China Pipeline Project as an example,the paper introduces the technology of pipe-laying in mountainous areas and summarizes the construction experience for reference by the construction workers.%我国地域辽阔，山川分布广泛，地形复杂，近年来长距离输送油气管道建设项目较多，特别是大口径管道穿越山区施工难度更大，山区管道施工的关键在于如何布管，有效解决山区管道布管技术，是解决山区施工最大的难点，为安全顺利施工将起到重要作用。以川气东送管道工程山区段为例，介绍山区布管技术，总结施工体会，供施工者参考。
