DISCUSSION ON ANTI-CORROSION OF TUBING AND CASING

    Graphical Abstract
    • Abstract
  • The inner coating is the successful practice of anti-corrosion.Any attempt to change it to external coating or plating isnt’ practicable.According to the theory of galvnic corrosion,the primary cell test in simulated well indicates that the corrosion would be centralized once the external coating had broken down,so that the tubing life was shortened.The paper suggests that the anti-corrosion must be considered both tubing and casing.
