Abstract: With the accelerating development of oil & gas pipeline construction in China, the intelligent pipeline construction which innovatively integrates oil & gas pipeline network with advanced technologies, such as internet+, big data and cloud computing, has become a important method and path to realize visualized, networked and intelligent management of pipelines under new situations. To construct intelligent oil & gas pipelines, the first step is to realize the intellisense of pipeline. In the perceptual layer, the pipeline itself, key equipment, environment, maintenance resources and other information are fully sensed, and acquisition, processing and transmission are integrated so as to provide a reliable data foundation for the decision of pipeline operation. The second step is the networking of information. In the network layer, all operators, objects and environment information are accessed to the network platform so as to realize the consistency of information flow and resource flow. The third step is the standardization of data. All data are cleaned, transformed and marked in the data layer. In the algorithm layer, data is deeply mined by means of artificial intelligence algorithm to extract fault information, predict operation state and optimize resource allocation. Finally, the targets of the intelligent pipeline operation is realized on the specific professional platform, including comprehensive and uniform data, interactive and visual perception, integrated and interconnected system, precise and matched supply, intelligent and efficient operation, and controllable prediction and prewarning.
