中国石油天然气集团公司规划分阶段地建成区域天然气管道运输管线。首先将建成四川→武汉→上海的天然气管道和西安一信阳输气干线共2787km,把四川的天然气先送到武汉,再把陕甘宁的天然气结合起来送到上海。到2002年,输气能力将达到40亿m~3。同时.青海的天然气也将送到兰州。第二阶段,建成兰州至西安的输气管道,形成柴达木、陕甘宁、川渝三大气区向长江中下游联合供 China National Petroleum Corporation plans to build a regional natural gas pipeline transportation pipeline in stages. First of all, a total of 2,787km of natural gas pipeline from Sichuan → Wuhan → Shanghai and Xi’an-Xinyang Gas Pipeline will be built to send Sichuan’s natural gas to Wuhan first and then the natural gas from Shaanxi, Gansu and Ningxia to Shanghai. By 2002, gas transmission capacity will reach 4 billion m ~ 3. At the same time, Qinghai’s natural gas will also be sent to Lanzhou. In the second stage, the gas pipeline from Lanzhou to Xi’an was completed, forming a coalition of three Qaidam, Shaanxi-Gansu-Ningxia and Sichuan-Chongqing gas stations in the middle and lower reaches of the Yangtze River
