Electrochemical polarization study on crude oil pipeline corrosion by the produced water with high salinity
Source abstract
Abstract
Abstract The effects of chloride ion, temperature, pH value, CO 2 and O 2 on the corrosion induced leakage of the inner wall of crude oil pipeline with the produced water were investigated by electrochemical polarization. The results showed that chloride ion corrosion would gradually experience the smooth invariant stage, the slow rise stage, and the rapid rise stage which due to the chloride ion destroy the corrosion product film. The corrosion rate would reach a maximum when the temperature was 65 °C or the pH value was 3.5. O 2 was the dominant factor induced the increase of corrosion rate when compared with the effect of CO 2 . Moreover, long term and periodic (30 consecutive days) electrochemical CO 2 corrosion tests suggested that the CO 2 corrosion rate reached a maximum at 4 days. The obtained results would facilitate the formulation of control measures for pipeline corrosion in the oil field.
