摘要： The invention also provides a composition for treating a subterranean formation penetrated by a wellbore. The composition is especially useful in acidizing treatments, which when combined with a corrosive aqueous fluid, inhibits the corrosion of metal surfaces, most especially, “duplex” chrome steel surfaces. An advantageous embodiment of the invention comprises at least 0.01% by weight of 3-hydroxypropionic acid and at least 1% by weight of an acid or acid precursor that different from 3-hydroxypropionic acid. The invention also provides a method for treating a subterranean formation penetrated by a wellbore. The method comprises the steps of forming the composition and introducing the composition into the subterranean formation through the wellbore.
