Corrosion Protection for Dina 2 Gas field Ground Device

The corrosion reasons of oil and gas pipelines were studied by analyzing the corrosion status in Dina 2 gas field. The effective anticorrosion methods for the pipelines in CO2 corrosion environment were demonstrated. Using lined stainless steel clad pipe or 22Cr pipe was proposed to prevent corrosion. Corrosion monitoring was carried out to those pipelines which were easy to corrode. Through mastering the corrosion status, repairing and replacing the corroded pipeline timely, the negative impact on oil and gas production caused by corrosion was reduced.
