DEVICE WITH CROSS FLOW ASSEMBLY FOR FLOW CONTROL INSIDE WELL Russian patent published in 2020 - IPC E21B43/12 E21B33/12 E21B34/06 

FIELD: oil and gas industry.

SUBSTANCE: group of inventions relates to the exploration and production of oil and gas, in particular to a device or system for controlling flow inside the well. Device for control of fluid flow in well includes internal tubular element with formed in it flow channel and external tubular element, made with possibility of location around internal tubular element for determination of annular space between external tubular element and internal tubular element. Device further comprises a cross flow assembly connected to the inner tubular member and the outer tubular member and configured to allow fluid flow between the inner tubular member flow path and the outer tubular member outer part; and a flow control device connected to the cross flow device and configured to control the fluid flow flowing through the cross flow device.

EFFECT: higher efficiency of well fluid flow control.
