Research on Status Quo and Problems of Abandoned Disposal Technology of Oil and Gas Pipelines

With the intensification of pipeline aging problems and the adjustment of energy structure, a large number of oil and gas pipelines are facing discontinuation and abandonment. How to deal with it safely and environmentally friendly has become an important topic. This article first compares the relevant regulations and standards for domestic and foreign oil and gas pipeline waste disposal, and then systematically analyzes the technical points in pipeline residue cleaning, cleanliness evaluation, pipeline demolition, pipeline sealing, etc. Finally, based on the actual project, the original and on-site waste methods and disposal technologies of pipeline demolition were compared and analyzed, and the applicable occasions and recommended practices of different pipeline waste disposal technologies were introduced.
