CO2 corrosion damage to petroleum tubular goods generally exists in the process of oil and gas production,at present,the most effective way to prevent CO2 corrosion is using corrosion resistant alloy,containing Cr steel is a type of corrosion resistant tubular goods commonly used in oilfield,and containing Cr steel corrosion research is always the focus of oil and gas field users. In this article, according to the characteristics and selection of CO2 corrosion in oil and gas field,it introduced CO2 corrosion research of several common corrosion resistant tubular goods,such as low Cr steel,13Cr/super 13Cr stainless steel,dual phase steel etc. and put forward problems existing in development and research of containing Cr steel, which provide certain reference for selecting corrosion resistance tubular goods.
