The oil and gas pipeline system is the artery of energy for the national economy development. With China’s increasing dependence on foreign oil and gas, accessibility of oil and gas strategic passages and availability of safe and stable energy supply are the urgent affairs. In the construction process of the onshore oil and gas strategic channels, by the independent innovation based on the “1+ N” cooperative model, the pipeline design, construction, equipment localization and high-pour-point and viscous crude oil transportation and other key technologies have been formed, and the large oil and gas pipeline networks with the scale of a total length of 6×104 km, transport capacity of 1.7×108 t of oil, transmission capacity of 1.4×1011 m³ of natural gas have been built. During the operation and management of the large pipeline networks, through the establishment of e-SAME security consistency systems, the operation and management organization, asset integrity management, market guarantee and emergency maintenance and other subsystems have been developed, and the enterprise security goals have been ensured.
