Benefiting more than 400 cities and a population of nearly 500 million, the cumulative gas transmission volume of the West-East Gas Pipeline exceeds 800 billion cubic meters.

On March 20, 2023, the reporter learned from the National Pipeline Network Group that by the end of 2022, the cumulative gas transmission volume of the West-East Gas Pipeline System consisting of the first, second, and third lines of the West-East Gas Pipeline will exceed 800 billion cubic meters, replacing 10.7 billion cubic meters of standard coal. billion tons, reducing carbon dioxide emissions by 1.17 billion tons and dust by 580 million tons.

At present, the total mileage of the West-East Gas Pipeline System exceeds 20,000 kilometers, equivalent to about half a circle around the Earth's equator. The pipeline crosses the Yellow River 5 times and the Yangtze River 3 times. It is the natural gas pipeline with the widest coverage in my country, benefiting more than 400 cities, more than 3,000 large and medium-sized enterprises and nearly 5 million people.

The West-East Gas Pipeline has played a positive role in promoting the adjustment of my country's energy structure, increasing the proportion of natural gas in my country's primary energy consumption structure from 2.4% in 2003 to 8.9% in 2021. At present, the National Pipeline Network Group is stepping up the construction of the middle section of the third line of the West-East Gas Pipeline and the fourth line of natural gas pipeline projects. After the project is put into operation, it will further enhance the natural gas supply capacity of the West-East Gas Pipeline System, better ensure national energy security and economic security, and inject stronger clean momentum into achieving the dual carbon goals and building a beautiful China.

The first line of the West-East Gas Pipeline is a landmark project of my country's western development. The main source of gas supply is the Tarim Gas Field. The main line of the pipeline starts from Lunnan Town, Luntai County, Tarim, Xinjiang in the west, and ends in Baihe Town, Qingpu District, Shanghai in the east, with a total length of 4,200 kilometers. On October 1, 2004, the first line of the West-East Gas Pipeline was completed and put into operation.

The Second West-East Gas Pipeline is my country's first strategic channel to introduce overseas natural gas resources, and the gas source comes from Central Asia. The project starts from Horgos Port in Xinjiang in the west, ends in Guangzhou and Hong Kong in the south, and reaches Shanghai in the east. The main pipeline and multiple branch lines have a total length of 9,102 kilometers. It is currently the longest natural gas pipeline in the world, with the largest supply coverage area and the largest number of beneficiary populations. .

The third line of the West-East Gas Pipeline starts from the Horgos Port in Xinjiang in the west and ends in Fuzhou, Fujian Province in the east. The total length of the pipeline is over 7,000 kilometers, and the annual designed gas transmission capacity is 30 billion cubic meters. The upstream is connected with Line C of the China-Central Asia Natural Gas Pipeline.

On September 28, 2022, the West-East Gas Pipeline Project started construction. This is another strategic energy channel connecting Central Asia and China after the first, second, and third lines. The project starts from Irkeshtan Port in Wuqia County, Xinjiang, passes through Lunnan Town, Luntai County, Turpan, and ends at Zhongwei, Ningxia. With a total length of about 3,340 kilometers, it is expected to be completed and put into operation in 2024.Editor / He Yurong
