Abstract (en)
[origin: WO2018065699A1] An apparatus for controlling the injection pressure of a aqueous polymeric solution in an oil well, said apparatus being formed by: - at least one pressure modulation valve, allowing, per valve, a maximum pressure loss of 5 bars practically without any mechanical deterioration, said one or more valves being connected in line with; - a tube containing vortex modules, each creating a maximum pressure loss of 5 bars, practically without any mechanical deterioration, a vortex module being a section of tube, closed at one of its ends by a lid perforated with a hole, and being able to be inserted into the detachable tube; the purpose of the apparatus being that of being able to reduce the pressure to 100 bars with total mechanical deterioration of less than 10%. A method for using said apparatus.
