Abstract (en)
[origin: FR2608622A1] Method for stabilizing clayish formations by injection into the formation of a cationic polymer. The latter is formed by quaternisation of the product obtained from the reaction of a polyamine with a copolymer formed of patterns derived from unsaturated alpha-beta-dicarboxylic acids and from at least one ethylenic unsaturated monomer.

Procédé pour la stabilisation de formations argileuses par l'injection dans la formation d'un polymère cationique. Ce dernier est formé par quaternisation du produit de la réaction d'une polyamine et d'un copolymère formé de motifs dérivant d'acides alpha-bêta-dicarboxyliques insaturés et d'au moins un monomère à insaturation éthylénique.
