As China's long-term high economic growth demands energy, people's demand for quality of life and ecological environment is also increasing. The century projects of west-to-east gas transmission, west-to-east gas transmission from sichuan and the introduction of Russian natural gas show that natural gas is an important energy source with high quality, clean and environmental protection. The smooth implementation of west-east gas transmission project has improved the construction level of natural gas pipe network in China and laid a foundation for the formation of national natural gas pipe network. Taking the west-east gas transmission project as the starting point, China's natural gas pipeline construction level is gradually approaching the international advanced level, and it is developing towards the direction of long distance, large diameter, high pressure and highly automated network management, which has laid a solid material foundation for the rapid development of China's natural gas industry.

It is understood that the west to east gas pipeline project construction in China as an opportunity, in overall consideration to the east, offshore and onshore natural gas resources, actively implement the strategy of "going out", introduce the foreign natural gas resources, further consummates our country natural gas pipe network development plan, the national natural gas resources, network of supply and the market scale and diversification.
