Dissolvable Material and Surface Protection Used in Oil/Gas Field

Abstract:

A dissolvable material used in oil/gas field was introduced. The corrosion property of the dissolvable material was characterized by using immersion method and scanning electron microscope. The dissolvable material could quickly react with KCl solution, and the reaction rate improved with the increase of the temperature. In some cases, the downhole tools made by dissolvable materials should not react with well fluid in a short term. Then a protective multilayer coating was fabricated on the material surface. The protective effect of the coating was evaluated with high temperature immersion method. The results indicated that the coating could effectively inhibit the dissolvable material reacting with KCl solution.
