The Role of Oxygen in Localize Corrosion and Degradation of Drill Pipes
Dissolved oxygen in drilling mud acts as an accelerator and main factor in localize corrosion and degradation of drill pipes. Presence or formation of corrosive ions in chemical composition of drilling mud and precipitation of mineral scales and corrosion by products, mutually increase oxygen-induced corrosion. In the present paper, on the side of discussion on corrosion and degradation effects due to presence of oxygen in drilling mud, mechanism and morphologies of oxygen-induced corrosion on a S-135 type drill pipe is discussed.
