West gas east and four lines are fully started

Today (September 28), the national “14th Five -Year France” oil and natural gas development plan key project — the natural gas pipeline project of Xiqi East Investment Fourth Line is officially started. After completion Later, the annual transportation capacity of my country's western pipeline network system will reach 100 billion cubic meters, which will further improve the Northwest Energy Strategic Channel in my country and effectively improve my country's natural gas energy supply guarantee capabilities.

The West Qi East Investment Fourth Line is another energy strategic channel connecting Central Asia and China after the West East Line, the second and third -line pipelines. It is a major measure to promote the construction of the green energy Silk Road in the new era. For my country It is of great strategic significance to make full use of international oil and gas resources and achieve energy security under open conditions. The project starts from Ilkhtan, Wugcha County, Xinjiang, and passes through the South and Turpan to Ningxia Central Guards. The total length of the pipeline is about 3340 kilometers, the pipe diameter is 1219 mm, and the design pressure is 12 MPA. After the project is completed, it will effectively enhance the reliability and flexibility of the pipe network system, improve the ability of energy transportation anti -risk, further promote the optimization of energy structure in the east and west regions, and help the economic and social development of pipelines and green low -carbon transformation along the pipeline.

The west gas -east transmission four -line project is constructed in accordance with the principles of unified planning and step -by -step implementation. The Turpan -Central Guard section started this time is a core component of the project, with a total length of 1745 kilometers. It passes through 17 counties (cities) in Xinjiang, Gansu, Ningxia Province (autonomous region). After the reconstruction, it can reach 30 billion cubic meters. It is expected to be completed and put into production in 2024. It can effectively unblock the road of the gas resources of the Tarim country, alleviate the tension and load of the winter peak of the Western Gas East, and in order to ensure the demand for economic and social energy and the warmth of the people. Winter security escort.

During the implementation process, the Xishi East Investment Four -Line Project combines project characteristics, difficulties, and priorities to comprehensively promote and applies the scientific and technological innovation achievements of pipeline construction. For the first time, a large -scale application of 18 -meter -plus tube is expected to reduce the welding port of more than 8,000, and the ring weld decreases by 33.3%, which effectively improves the essence of pipelines. ; Promote the dual -connected pipeline construction method of large -caliber pipelines, and save 4 days in a single kilometer saving welding working period, which greatly improves construction work. Strict implementation of environmental protection facilities as the main project, construction, construction, and production of the "three simultaneous" systems, supporting facilities and in service pipeline parallel laying, priority use of existing roads and facilities to reduce waste of resources and ecological destruction.

Since the beginning of this century, according to the major decision -making deployment of the western development of the western region, the west gas has been completed and put into operation in the first, second, third lines, and east sections. The pipeline system has become one of the "four major projects" allocated by my country's natural resources across regions. The total transportation capacity is 77 billion cubic meters per year. Since its establishment, it has transported about 750 billion cubic meters of natural gas since its completion. The atmospheric environment, promoting the development of related industries and promoting economic development have made outstanding contributions.
