Present situation and future development direction of corrosion inhibitor for acidizing in oil and gas reservoir transformation.

This paper reviews the development of corrosion inhibitors used in the process of acidification transformation of oil and gas deposits at home and abroad, further discusses the mechanism of corrosion inhibitors, analyzes the composition of corrosion inhibitors, and expounds in detail the quaternary ammonium salt type,Mannich alkali type and other corrosion inhibitors with wide application range. Besides,according that the chemically synthesized corrosion inhibitors is partly toxic to organisms and the environment, this paper also points out that the development of corrosion inhibitors for acidizing in the future will be green, efficient and environmentally friendly.
