[Abstract]:Stray current interference causes great harm and damage to oil and gas pipeline. How to effectively detect, evaluate and formulate appropriate protection countermeasures is the key to the protection of stray current in oil and gas pipeline. Based on the different detection methods of stray current and the practice of drainage application, the comprehensive detection, evaluation and protection research of stray current in oil pipeline are carried out. The results show that by combining the whole line detection with special detection, CIPS (dense spacer earth potential test) and SCM (stray current intelligent tester, potential gradient, potential and current monitoring) are used comprehensively. Combined with site excavation analysis, the type of stray current interference and its influence on pipeline can be accurately determined, and the local corrosion of oil pipeline detected by serious DC stray current interference and AC stray current interference can be obtained. The effect analysis and evaluation of stray current drainage treatment measures are carried out through the measurement of pipe-ground potential, and the countermeasures for protection against stray current interference in pipeline are suggested. It is suggested that the source control of stray current of pipeline should be strengthened, at the same time a variety of detection and monitoring techniques should be used synthetically, all kinds of interference factors and corrosion conditions should be effectively analyzed, and scientific and reasonable treatment methods and protective countermeasures should be formulated. Provide basis for pipeline integrity management.
