Description

Technical field [0001] The invention relates to the technical field of online monitoring of oil well pipeline corrosion, in particular to an online monitoring system and method for the anti-corrosion effect of oil well pipelines. Background technique [0002] The corrosion damage of oil well pipelines will seriously reduce the structural strength, bearing capacity and reliability of the pipelines, shorten the service life of the pipelines, increase operational risks, greatly increase maintenance costs, shorten maintenance and replacement cycles, and threaten the safety of the entire transportation system. Oil well pipeline leakage has become a major source of risk in the oil field, seriously affecting the safety of oil field production. In view of the current situation of frequent occurrences of on-site oil well pipeline corrosion, damage and third-party damage, conventional manual inspections can no longer meet on-site needs, and current online monitoring technologies have their...
