HYDROPHOBICALLY MODIFIED QUATERNIZED POLYSACCHARIDE CORROSION INHIBITORS
A treatment fluid that includes an aqueous fluid, an inorganic acid, and a hydrophobically modified quaternized polysaccharide may be useful in mitigating corrosion of metal surfaces by the inorganic acid. For example, a wellbore operation may include introducing the treatment fluid into a wellbore...

| description | A treatment fluid that includes an aqueous fluid, an inorganic acid, and a hydrophobically modified quaternized polysaccharide may be useful in mitigating corrosion of metal surfaces by the inorganic acid. For example, a wellbore operation may include introducing the treatment fluid into a wellbore penetrating a subterranean formation and contacting a metal surface with a treatment fluid.
Cette invention concerne un fluide de traitement qui contient un fluide aqueux, un acide inorganique, et un polysaccharide quaternisé modifié par substitution hydrophobe qui peut être utile pour atténuer la corrosion des surfaces métalliques par l'acide inorganique. Par exemple, une opération de puits de forage peut comprendre l'introduction du fluide de traitement dans un puits de forage pénétrant dans une formation souterraine et sa mise en contact avec une surface métallique. |
