Title (EN) CORROSION INHIBITOR OR INTENSIFIER FOR USE IN ACIDIZING TREATMENT FLUIDS
(FR) INHIBITEUR DE CORROSION OU RENFORÇATEUR POUR UN USAGE DANS DES FLUIDES DE TRAITEMENT ACIDIFIANT
Abstract:
(EN) The invention also provides a composition for treating a subterranean forrnation 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.
(FR) La présente invention fournit également une composition pour traiter une formation souterraine pénétrée par un puits. La composition est particulièrement utile dans des traitements acidifiants, laquelle, lorsqu’elle est combinée avec un fluide aqueux corrosif, inhibe la corrosion des surfaces métalliques, plus particulièrement, des surfaces d'acier au chrome « duplex ». Un mode de réalisation avantageux de l'invention comprend au moins 0,01 % en poids d'acide 3-hydroxypropionique et au moins 1 % en poids d'un acide ou d’un précurseur d’acide différent de l'acide 3-hydroxypropionique. L'invention fournit également un procédé pour traiter une formation souterraine pénétrée par un puits. Le procédé comprend les étapes consistant à former la composition et à introduire la composition dans la formation souterraine à travers le puits.
