Applied research of Mannich reaction in synthesis of acidifying corrosion inhibitor

Acidizing process is one of effective technical measures for increasing production of oil and gas wells and increasing injection of injection wells.In acidification of the oil and gas well,corrosion inhibitor is synthesized by the Mannich reaction that has strong performance,obvious effect,stable structure,strong acid soluble,resistant temperature and resistant acid.The common Mannich base corrosion inhibitor has been introduced,including synthesis principle,preparation process,the best conditions for using and product performance,it has practical significance for a comprehensive understanding of Mannich base corrosion inhibitor technology.
