Research on integrity development strategy for long-distance oil and gas pipeline

Long-distance oil and gas pipeline is a key component of oil and gas strategic import channel. It have great significant to ensure the efficient and stable operation of pipeline for energy security. In order to meet the development needs of the integrity of long-distance pipelines, the development process, research hotspots, development status and existing bottlenecks in China were analyzed in this paper. The development plan was proposed from two levels of key technology and scientific research support conditions. As to the technical level, the full pipeline life cycle coverage, high-precision defect detection, risk management and control, emergency intelligent decision-making, and comprehensive application of core technologies such as information security assurance should be achieved. In another the localization of core equipment types, and the independent research and development system and key equipment should be fully applied in oil and gas pipelines. The localization of core equipment, fully apply self-developed systems and key equipment on oil and gas pipelines at home and abroad should be improved. The support in policies should be provided such as pipeline integrity management system, institutional mechanism construction and safety legislation. At the same time, the investment in stable scientific research in personnel cultivation and laboratory construction, strengthen the promotion and application of results, and strengthen scientific and technological exchanges and cooperation to better ensure the development and improvement of pipeline integrity technology should be enhanced.
