摘要： Methods and compositions for treating aqueous fluids that may be included in treatment fluids that are used for treating a subterranean formation. In some embodiments, the methods include: providing a treatment fluid including an aqueous fluid and a composition that includes an oxygen scavenger, a pH-adjusting agent, and a corrosion inhibitor, wherein the aqueous fluid is aerated; contacting a metal surface with the treatment fluid; and introducing the treatment fluid into a wellbore penetrating at least a portion of a subterranean formation.

摘要： Methods for providing corrosion inhibition in conduits, containers, and wellbores penetrating subterranean formations are provided. In some embodiments, the methods comprise contacting a metal surface with a fluid comprising a corrosion inhibitor additive. In certain embodiments, the corrosion inhibitor additive comprises a compound comprising a hydrophobic cation moiety, one or more lipophilic tails, and a linking moiety.
