RESERVOIR PRESSURE MAINTENANCE SYSTEM Russian patent published in 2020 - IPC E21B43/20

Abstract RU 2714898 C1

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil and gas industry, in particular, to reservoir pressure maintenance system. System includes cluster pumping station with high-pressure pump with discharge water conduit, interconnected through combs with water conduits with injection wells operating at different pressures and / or opening formations with different collector properties, water intake wells interconnected by water conduits with appropriate injection wells. Injection wells with close intake capacity, injection pressure and physicochemical composition permissible for pumping of water are grouped by means of appropriate water conduits of the comb, which through controlled gates are communicated with the discharge water conduit, and water intake wells with the same type of water and formation pressure as per physical and chemical composition are interconnected with the corresponding water ducts in the comb, allowing siphon pumping from the water intake wells to the appropriate injection wells.

EFFECT: technical result is higher reliability and simplified system.
