SYSTEM FOR FLUID FLOW CONTROL IN WELL COMPRISING FLUID MODULE WITH BRIDGED NETWORK FOR FLUID AND METHOD FOR SUCH SYSTEM USAGE Russian patent published in 2015 - IPC E21B21/08 

Abstract RU 2568619 C2

FIELD: oil and gas industry.

SUBSTANCE: system comprises fluid module (150) with the main channel (152), valve (162) and bridged network. Valve (162) has the first position, wherein fluid may pass through the main channel (152), and second position, wherein passage of fluid through the main channel (152) is locked. The bridged network has the first and second branch channels (163, 164), each of them having inlet (166, 168) and outlet (170, 172) interconnected to the main channel and each of them including two hydraulic resistors (174, 176, 180, 182) with pressure take-off terminal (178, 184) located between them. At operation pressure drop between terminals (178, 184) of the first and second branch channels (163, 164) shifts valve (162) between the first and second positions.

EFFECT: higher efficiency of efficiency for in-well fluid flow adjustment.
