Description
Technical Field

Background
Acidification is one of the effective technical measures for increasing the yield of oil and gas wells and increasing the injection of water injection wells in the development process of carbonate reservoirs. The acidification process comprises acid washing, matrix acidification and fracturing acidification. The acidizing corrosion inhibitor is one of the most important additives in the acidizing construction process, and all industrial acids used in oil and gas well production increase measures are added with the corrosion inhibitor to reduce the acid etching speed of a shaft column. With the development of drilling technology and the progress of oil extraction technology, a large number of deep wells, ultra-deep wells and ultra-deep wells are put into development, and higher requirements are put forward on the performance of the corrosion inhibitor for acidification. The main stream products of the acidification corrosion inhibitor at present are: a compound system taking ketone aldehyde amine condensate as a main agent and a compound system taking pyridine and quinoline compound quaternary ammonium salt as a main agent. However, in production practice, acidizing stimulation techniques have not been applied and developed until after the advent of the acidizing corrosion inhibitor in the 30s of the 20 th century due to severe corrosion of the well by acid.
