Abstract: The full life cycle data management is the foundation of the full life cycle integrity management of oil and gas pipelines. The research and development status of the full life cycle data management technology for oil and gas pipelines were systematically expounded from the aspects of data model building, digital handover standard, digital handover interface development, data integration maintenance and analysis application. According to the data management requirements of China- Russia Eastern Gas Pipeline, the PIDM data model was optimized and upgraded from two aspects of data content expansion and data organization structure optimization, and the association rules of data in all stages of the full life cycle of the pipeline were added to the PIDM data model. A series of standards and specifications were developed and revised, including Oil and gas pipeline equipment and facilities operation data specification (CDP-G-OGP-IT-148—2019-1), Specification for pipeline integrity management - Part 6 : Data collection (Q/SY 05180.6—2019), therein implied the specific service requirements and corresponding data rules of China-Russia Eastern Gas Pipeline. The PIS function of the pipeline integrity management system was optimized: advanced GIS service functions such as vector slicing, WFS, and Web Scene were expanded at the back-end server, while rich data display, analysis, and maintenance functions such as customized drawing, multilingual support, local data display, shared view, roller shutter, timeline, and event editor were developed at the front-end. The above achievements performed well in the practical application of the north section of China-Russia Eastern Gas Pipeline. Finally, the bottleneck problems to be solved urgently in the future life cycle data management of the oil and gas pipeline was put forward.
