(FR) MÉTHODE DE TRAITEMENTS DES PUITS PAR EMULSIONS DE PETITE TAILLE CONTENANT DES ADDITIFS
Resumo: front page image
(EN)The invention concerns a method for treating a reservoir rock which includes the following steps: making a concentrated water-in-oil emulsion comprising: between 50 and 80% of aqueous phase in which at least one treatment additive is dissolved, between 20 and 50% of oil phase containing at least one polymeric surfactant; shearing the concentrated emulsion so as to obtain an emulsion having drops of substantially monodispersed size and essentially less than 1 &mgr;m; diluting the monodispersed emulsion with an oil phase to obtain a aqueous phase dispersed at a rate less than 50%; and injecting the diluted emulsion into the reservoir rock.
(FR)L'invention concerne une méthode de traitement d'une roche réservoir dans laquelle on effectue les étapes suivantes : - on fabrique une émulsion concentrée eau dans l'huile comportant : entre 50 et 80% de phase aqueuse dans laquelle au moins un additif de traitement est dissous, entre 20 et 50% de phase huileuse contenant au moins un tensioactif polymérique, - on cisaille l' émulsion concentrée de manière à obtenir une émulsion ayant des gouttes de taille sensiblement mono disperse et principalement inférieure à 1 &mgr;m, - on dilue l'émulsion mono disperse par une phase huile pour obtenir une phase aqueuse dispersée à un taux inférieur à 50%, - on injecte l'émulsion diluée dans la roche réservoir.
