Abstract
The transportation of crude oil mainly relies on long-distance buried oil pipelines, which are generally made of steel pipes. Oil leakage often occurs due to corrosion, causing environmental pollution and unsafe accidents. A digital monitoring system for pulse current cathodic protection of oil pipelines was studied, with a focus on the composition and functions of the digital monitoring system for pulse current cathodic protection of oil pipelines. In 2022, the system was applied on two oil pipelines in Tongzhai operation area of the Third Oil Production Plant of Changqing oil field. The system realized the pulse current cathodic protection of oil pipelines to prevent corrosion. At the same time, it can digitally monitor the pulse current cathodic Conservation status status and adjust the working state of the potentiostat, and cooperate with the pulse current cathodic protection monitoring expert system for auxiliary analysis, which has received good economic and social benefits.
