METHOD OF OIL POOL DEVELOPMENT Russian patent published in 2015 - IPC E21B43/20 

FIELD: oil and gas industry.

SUBSTANCE: method includes injection of disperse polymer system to the formation through injectors interconnected through a pressure manifold and valve manifold to the well pad pumping station (WPPS). According to the method using the above equipment the water conduit is equipped with a water meter and an adjustable gate coupled functionally to the water meter. The mixing plant is connected to the water conduit upstream and downstream the WPPS, which is input for the valve manifold. The disperse polymer system prepared at the mixing plant is injected through the pipeline with the gate at the water conduit being the input for the valve manifold with maintenance of water supplied from the valve manifold at the same consumption rate. It allows injection of the disperse polymer system with required concentration.

EFFECT: improved oil recovery in result of injection of disperse polymer system to the formation through injectors with simplified technology and reduced costs.
