The annual gas transmission capacity of the West-to-East Gas Pipeline breaks through 100 billion cubic meters ｜ China has formed a new pattern of ＂one national network＂ of natural gas that spans east

　　CCTV News:As of today (December 28th), the West-to-East Gas Pipeline Project, with a total investment of more than 400 billion yuan and continuous construction for 20 years, has become one of the largest natural gas pipeline systems in the world. Let’s review the development history of engineering in this century.

　　In February, 2000, the country started the West-to-East Gas Transmission Project, which was regarded as a landmark project for the development of western China.

　　On July 4, 2002, the West-to-East Gas Pipeline Project started. On December 30, 2004, the first line of west-to-east gas transmission was put into commercial operation. The first line of west-to-east gas transmission takes Tarim gas field in Xinjiang as the main gas source and the Yangtze River Delta as the main target market.

　　With the increasing demand for natural gas clean energy in the downstream market, the west-to-east gas transmission project was started in March 2005, and the gas transmission capacity was increased by more than 40%. In 2007, the Second West-to-East Gas Pipeline Project was officially launched, and it was put into operation in 2011, transporting natural gas from the Central Asian natural gas pipeline to the central and southern parts of China and the Pearl River Delta region.

　　Since the 18th National Congress of the Communist Party of China, the construction of the West-East Gas Pipeline has been further accelerated. In 2012, the Third West-East Gas Pipeline Project started construction, and fully realized the autonomy of engineering technology and the localization of technical equipment. After completion, it was connected with the original first and second lines, realizing the leap-forward development from pipeline gas transmission to pipeline network gas transmission.

　　This year, the middle section of the third line of west-to-east gas transmission started construction. The annual gas transmission capacity of the west-to-east gas pipeline system has exceeded 100 billion cubic meters, a record high. China has formed a new pattern of "one national network" of natural gas that spans east and west, runs through north and south, and connects overseas.
