Title
(EN) CONTROLLING THE FORMATION OF POLYMER-METAL COMPLEXES IN WELLBORE OPERATIONS
(FR) CONTRÔLE DE LA FORMATION DE COMPLEXES POLYMÈRE-MÉTAL DANS DES OPÉRATIONS DE PUITS DE FORAGE
Abstract
(EN)
Treatment fluids and associated methods for treating a subterranean formation. An example method includes introducing a treatment fluid into a wellbore penetrating the subterranean formation. The treatment fluid includes a competitive metal binder selected from the group consisting of polyamino polyether methylene phosphoric acid, hydoxyethylamino- di(methylene phosphoric acid), and a combination thereof; a polymer capable of forming a polymer-metal complex; and an aqueous fluid. The method further includes contacting a metal ion with the treatment fluid after introduction of the treatment fluid into the wellbore and binding the metal ion with the competitive metal binder.

L'invention concerne des fluides de traitement et des procédés associés destinés au traitement d'une formation souterraine. Un exemple de procédé consiste à introduire un fluide de traitement dans un puits de forage pénétrant dans la formation souterraine. Le fluide de traitement comprend un liant métallique compétitif choisi dans le groupe constitué par l'acide polyamino polyéther méthylène phosphorique, l'hydoxyéthylamino-di(acide méthylène phosphorique), et une combinaison de ces derniers; un polymère apte à former un complexe polymère-métal; et un fluide aqueux. Le procédé consiste en outre à mettre en contact un ion métallique avec le fluide de traitement après l'introduction du fluide de traitement dans le puits de forage et à lier l'ion métallique avec le liant métallique compétitif.
