Abstract
Installation for enhanced oil recovery comprising in succession: a polymer storage hopper, a grinding device, a dissolution/maturation tank for the dispersed polymer, and a pump for transferring pressurized polymer solution in the pipeline conveying the injection water for introducing the mixture of polymer and injection water into a well. The grinding device has a chamber for grinding and draining the dispersed polymer comprising a rotor and a stator, and on all or part of the periphery of the chamber, a ring fed by a secondary water circuit. The ring communicates with the chamber for spraying of pressurized water on the blades of the stator. A method implementing the installation is also provided.
