Abstract
The devices and methods for controlling flow through a multi-channel system deployed in a petroleum well are disclosed. The devices of the invention feature a manifold with a plurality of inlets operably connected to the passageways of the multi-channel system. Individual flows of the multi-phase petroleum fluid from the parallel passageways of the multi-channel system towards the inlets of the manifold are controlled by opening or closing of corresponding stopping valves installed on each inlet or group of inlets. After exiting the inlets through the stopping valves, the flows of the multi-phase fluid are consolidated and directed towards single or multiple outlets of the manifold and ultimately towards the outlet of the petroleum well. Individual opening or closing of the stopping valves has the effect of increasing or decreasing the total cross-sectional area available for producing fluid flow through the well.
