摘要

WATER TREATMENT PROCESS, OBTAINED FROM AN IMPROVED OIL RECOVERY PROCESS USING POLYMERS. Process for treating produced water, obtained from an improved oil recovery process from a reservoir, said water containing at least one water-soluble polymer, wherein an oxidizing agent is injected into the produced water in such amount that the viscosity of the said water which is reduced to below 2 cps, beneficially on the order of 1.5 cps, within a short period of less than 5 hours of oxidant injection and a reducing agent is then injected in the amount necessary to neutralize all the resulting excess oxidizing agent.
