管道新设备、新技术在“西气东输”项目中的应用

NEW EQUIPMENT AND TECHNOLOGY APPLIED IN WEST-TO-EAST GAS PIPELINE PROJECT

“西气东输”工程项目以新疆塔里木油气田为主供气源,以长江三角洲地区为主要目标市场,以干线管道、重要支线和储气库为主体,连接沿线用户,形成横贯我国西东的天然气供气网络。截至2006年底,该项目共投产运营5800km管道,累计输送天然气158×108m3。作为国内首条大口径、长距离、高压力输气管道,“西气东输”项目从设计、施工、运行等方面研发应用了多项新技术、新设备,对此进行梳理和总结可以为后续管道建设提供宝贵的借鉴经验。

The great project of “West-to-East” gas pipeline helps abundant gas in West China transmitted to East China successfully. Therefore, a gas supplying network traversing from west to east, taking the Tarim Gas Field as its main gas source, areas at the Yangtze River Delta as its key target markets, connects each gas consumer along the pipeline with its trunk line, important branch lines and gas storage as its main body. By the end of 2006, a 5800 km long pipeline with total gas transmission of 15.8 CBM had been put into production and operation. As Chinese first long-distance gas pipeline with extremely large diameter and high pressure, the West-to-East gas pipeline has introduced many kinds of technologies and adopted various new equipments during its design, production and operation, as for which this paper reviews and sums up for the continual pipeline construction in the future to learn lessons and experiences from the previous great work.
