Analysis And Scrutiny of Corrosion in Drilling Industry Oil Well and ways to prevent and treat corrosion in the industry, Section (II)

Damage or failure due to corrosion phenomena, one of the major causes of failure is the failure of drilling pipes. This phenomenon has occurred in most rigs. Any damage to the industry imposes enormous damage. In this regard, an extensive research in the field of corrosion in the oil well drilling industry. Research and analysis conducted in four papers have been collected. In this article the expression of research and analysis on issues such as Factors affecting the corrosion (metal destruction) such as PH, temperature, speed, heterogeneity and excessive stress, oxygen corrosion, corrosion cell, the cathode polarization dioxide, oxygen corrosion factors such as: detection and measurement of oxygen corrosion, treatment Corrosion of oxygen, the oxygen treatment, oxygen-absorbing material limitations, chromite inhibitor and corrosion inhibitor of oxygen, carbon dioxide corrosion (corrosion sweet), the amount of carbon dioxide gas in the drilling mud, the treatment dioxide carbon deposits, deposits diagnosis, treatment deposits (prevent the formation of deposits), corrosion caused by hydrogen sulfide (sour corrosion), factors affecting the hydrogen sulfide corrosion, stress corrosion, hydrogen embrittlement, electrolytes, stress, metallurgy, effect time, the presence of surface cracks, the amount of hydrogen required for the hydrogen embrittlement, a new weapon, hydrogen sulfide poisoning, diagnosis or determination of hydrogen sulfide, hydrogen sulfide treatment, flower oil as a preservative and the concentration of hydrogen sulfide is proposed treatment. In this paper, all the results were compared with experimental samples.
