Abstract

La présente invention concerne un polymère dégradable dans une partie d'un puits de forage et/ou d'une formation souterraine ; un fluide d'entretien de puits de forage comprenant un accélérateur de dégradation à base de sel particulaire et un activateur neutralisant, l'accélérateur de dégradation à base de sel particulaire étant formé en faisant réagir une solution d'accélérateur de dégradation choisi dans le groupe constitué par une alcanolamine ; un oligomère d'aziridine ; un polymère d'aziridine ; une diamine ; et une combinaison quelconque de ceux-ci, avec un acide, et l'activateur neutralisant pouvant dissocier l'acide de l'accélérateur de dégradation à base de sel particulaire par neutralisation de sorte à former un accélérateur de dégradation neutralisé ; l'introduction du fluide d'entretien de puits de forage dans un puits de forage et/ou une formation souterraine ; la mise en contact du polymère dégradable avec l'accélérateur de dégradation neutralisé ; et la dégradation du polymère dégradable.
