Abstract

Acidizing is a measure of increasing production and injection by injecting acid into formation through oil–water wells to remove formation blockages and dissolve the rocks to recover and enhance formation permeability. This chapter mainly introduces acids and additives used in acidizing. The acidizing principle and application scope of various acids are introduced. These acids can dissolve the corrosion products that block the wells or blockage in the formation infiltration surface to recover and improve formation permeability. Classification and function mechanism of various acid additives, such as retardant, corrosion inhibitor, iron stabilizer, emulsion inhibitor, clay stabilizer, cleanup additive, sludge inhibitor, wettability reversal agent and diverting agent, are also introduced in detail in this chapter.
