In the acidizing of a subterranean formation or well bore, the acidizing solution additionally contains a stabilized corrosion inhibitor composition to reduce its corrosivity towards metals. The inhibitor composition comprises an inhibiting effective amount of an acetylenic alcohol, a quarternary ammonium compound, an aromatic hydrocarbon, an antimony compound, and a stabilizer which substantially prevents precipitation of solubilized antimony-containing compounds from aqueous solutions. |
