Abstract

Un procedimiento de tratamiento de un fluido acuoso que comprende al menos un polímero hidrosoluble que porta funciones carboxilatos o sulfonatos en una fase acuosa, donde dicho procedimiento comprende una etapa de puesta en contacto de dicho fluido acuoso con al menos un citrato alcalino o metálico, lo que permite reducir la viscosidad de dicho fluido acuoso, para producir un fluido acuoso que tenga una viscosidad reducida, cercana a la del agua. También se refiere a un proceso para la recuperación mejorada de petróleo crudo contenido en un yacimiento geológico en el que se trata el agua de producción mediante dicho proceso de tratamiento de un fluido acuoso.A process for treating an aqueous fluid comprising at least one water-soluble polymer bearing carboxylate or sulfonate functions in an aqueous phase, wherein said process comprises a step of contacting said aqueous fluid with at least one alkaline or metallic citrate, which allows the viscosity of said aqueous fluid to be reduced, to produce an aqueous fluid having a reduced viscosity, close to that of water. It also relates to a process for the enhanced recovery of crude oil contained in a geological reservoir in which the production water is treated by said process of treating an aqueous fluid.
