Abstract: With the continuous development of pipeline industry in China, the third generation of pipeline technology system, represented by China–Russia Eastern Gas Pipeline, has been established, and China's overall technical level of using pipeline for energy transportation has reached the first class in the world. Herein, the development status of technologies in the fields of design and construction, material and equipment, transportation and storage, and security and maintenance of pipeline projects in China was summarized systematically. On this basis, the opportunities and challenges faced by the oil & gas storage and transportation technologies under the drive of the new energy security strategy featuring "Four Revolutions and One Cooperation" were analyzed, and prospect was made for the development directions of upgrading of traditional oil & gas storage and transportation technologies, digital transformation, storage and transportation of new energies, and unconventional pipeline technologies. Facing to the new situations and requirements, the pipeline enterprises should provide powerful support to guarantee the national energy security and improve the construction of modern energy system, while ensuring the safe and efficient transportation of oil and gas.
