Abstract
The present invention relates to a method of regulating the flow rate of formation fluids produced from a determined zone of an underground well whose cased wall is provided with orifices through which said formation fluids can pass, said method consisting in applying a tubular structure along the casing in said zone, which tubular structure prevents the fluids from flowing directly while also preserving a flow path along which the fluids can flow via the annular space outside the tubular structure so as to generate head loss. The invention also relates to a device for implementing said method, which device is essentially constituted by a radially-expandable tubular structure that can be applied against the inside wall of the casing, the structure being provided with means for preserving the flow of the fluids via a path running along the casing and along the structure, in order to generate head loss.
