Title
(EN) PREPARING A HYDRATABLE POLYMER CONCENTRATE FOR WELL TREATMENT APPLICATIONS
(FR) DISTRIBUTION DE POLYMÈRE DANS DES APPLICATIONS DE TRAITEMENT DE PUITS
Abstract
(EN)
This invention relates to compositions and methods for treating subterranean formations, in particular, oilfield stimulation compositions and methods using water-in-water polymer emulsions to uniformly dissolve a Theologically active polymer, such as a thickener or friction reducer, in the treatment fluid. The emulsions have a low viscosity and are easily pumped for mixing into a treatment fluid, where upon dilution with an aqueous medium, the polymer is easily hydrated without forming fish-eyes. The partitioning agent in the water-in- water emulsion does not generally affect the rheology of the treatment fluid. The invention also relates to further processing of the emulsion by wet grinding, high shear mixing and/or heating to enhance the hydration rate in the preparation of the well treatment fluid.
(FR)
Cette invention porte sur des compositions et des procédés pour traiter des formations souterraines, en particulier des compositions et procédés de stimulation de champ pétrolifère utilisant des émulsions polymères eau-dans-eau pour dissoudre de façon uniforme un polymère à activité rhéologique, tel qu'un épaississant ou un agent de réduction de frottement, dans le fluide de traitement. Les émulsions ont une faible viscosité et sont facilement pompées en vue d'une incorporation par mélange dans un fluide de traitement, où, lors de la dilution avec un milieu aqueux, le polymère est facilement hydraté sans former d'yeux de poisson. L'agent de partage dans l'émulsion eau-dans-eau n'affecte généralement pas la rhéologie du fluide de traitement. L'invention porte également sur un nouveau traitement de l'émulsion par broyage à l'état humide, mélange à cisaillement élevé et/ou chauffage pour augmenter le taux d'hydratation dans la préparation du fluide de traitement de puits.
