Application and Research of CO₂ Corrosion Inhibitors in Oil-gas Field

Injecting inhibitors to inhibit CO2 corrosion in oil-gas fields is a widely used method which has the advantages such as simpleness,being easy to use,economization on investment and yielding great results.The development of CO2 corrosion inhibitors is summarized in this paper.The inhibitors for CO2 corrosion are classified according to inhibitor single-component,snynergistic effects,application environments,environmental protection and so on.The trend of further development in this field is put forward.
