Research on the Status and Improvement of Pressure Plugging Technology for Long Distance Pipeline
During the service period of pipelines,oil and gas leakage accidents occur due to corrosion,mechanical damage,third-party damage,and emergency repairs are required.Pressure plugging technology is widely used due to its wide range of suitable media and safety and environmental characteristics.The paper discussed the current status and application of pressure plugging technology for China pipelines.Analyzed the shortcomings in plugging tee,plugging cup,controlling the knife feed,and removing residual oil.Propose optimized design and improvement measures for pressurized plugging technology.The research results have important guiding significance for improving the efficiency and safety reliability of pipeline pressure plugging.
