Abstract

Des inhibiteurs de corrosion améliorés pour des saumures de puits comprennent un phosphonate ou des sels connexes et un acide gluconique ou des sels connexes. Les inhibiteurs sont normalement injectés en fond de trou dans les saumures. Les phosphonates les plus privilégiés sont des polyphosphonates aminés utilisés en combinaison avec des sels métalliques alcalins d'un acide gluconique.
