Iron Ion Stabilizer
During the acidizing operation, as the acid solution comes into contact with the steel surface, some iron ions will be formed and enter the formation. With the progress of the acid-rock reaction, the activity of the acid solution will gradually decrease, the pH value will increase, and free iron ions will precipitate in the form of Fe(OH)₃, causing secondary pollution. By adding an iron ion stabilizer to the acid solution, it can effectively complex the free iron ions to form stable iron ion complexes, avoid the generation of secondary precipitation, and improve the acidizing effect.
