Abstract

Divulgation d'une méthode pour abaisser le temps de remise en état après cisaillement de systèmes de fluides tensio-actifs visco-élastiques, amphotères, switterioniques et cationiques par addition d'une quantité efficace d'un améliorant rhéologique polymère, amphiphile contenant au moins une partie constituée d'un poly(ester de vinyle) partiellement hydrolysé ou d'un polyacrylate partiellement hydrolysé. L'améliorant rhéologique augmente aussi la viscosité du fluide, et une très faible concentration de celui-ci est nécessaire. Les agents tensio-actifs préférés sont des bétaïnes et des amines quaternaires. Ces fluides sont utiles pour des traitements sur les champs de pétrole, par exemple pour la fracturation et pour les filtres à gravier.
