METHOD OF EQUALIZING FLUID WHEN INJECTING Russian patent published in 2018 - IPC E21B34/08 F16K21/04 E21B43/32 

Abstract RU 2643377 C1

FIELD: oil and gas industry.

SUBSTANCE: at implementation of the method, along the whole length of the well at the outlet from the wellbore into the annular space and further into the formation, equal hydraulic resistances to the flow is set, which exceed hydraulic resistance when fluid is moving through the wellbore and also resistance of fluid injection into the formation, which depends on rock properties.

EFFECT: uniform distribution of the flow of fluid injected into the formation along the wellbore for optimum production of reserves with a significant simplification of the inflow control devices.
