INSTALLATION FOR ENHANCED OIL RECOVERY USING WATER-SOLUBLE POLYMERS, METHOD IMPLEMENTING SAME

摘要

Installation for enhanced oil recovery comprising in succession: a polymer storage hopper (1), a grinding device (3) comprising, a chamber (16) for grinding and draining the dispersed polymer comprising a rotor (17) and a stator (20), on all or part of the periphery of the chamber, a ring (22) fed by a secondary water circuit (22), the ring communicating with the chamber (16) for the spraying of pressurised water on the blades (21) of the stator (20), a dissolution/maturation tank (6) for the dispersed polymer, a pump (5) for transferring the pressurized polymer solution in the pipeline conveying the injection water for introducing the mixture (polymer + injection water) into the well (P). Method implementing the installation.
