Combined with the development strategy of oil and gas pipeline technology in China, the current situation and development trend of oil and gas pipeline technology are summarized.In terms of engineering design and construction, China has mastered the pipeline design technology based on strain and reliability, and developed high-grade pipeline welding, mechanical patching, trenchless crossing technology and equipment.In the field of materials and equipment technology, X80, X90 / X100 and other high-grade steel pipe development and application technologies have taken the lead in the world.At the same time, a breakthrough has been made in the localization of key pipeline equipment, and the future technical research direction is to improve the intelligence level of pipeline equipment;in the pipeline transportation technology, the pipeline transportation technology of highly condensable and viscous crude oil has reached the international leading level,but there is certain gap between the technology of sequential transportation and simulation optimization of refined oil productsand that of operation and maintenance, such key technologies as pipeline integrity management, safety monitoring and corrosion protection are basically synchronized with that of foreign countries.In the future, we will continue to promote the application of pipeline system reliability technology.
