Devices and methods for controlling a multi-channel system in a petroleum well

摘要

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.

1. A device for controlling flow in a multi-channel system deployed in a petroleum well, said multi-channel system comprising a plurality of parallel passageways configured for transporting individual multi-phase fluid flows within said petroleum well, said device comprising a manifold with a plurality of inlets operably connected with all of said parallel passageways, each inlet is equipped with a stopping valve configured to open or close flow of said multi-phase fluid therethrough, said manifold is further equipped with a first outlet configured to transport a combined flow of said multi-phase fluid after exiting from said stopping valves, whereby individual opening or closing of one or more of said stopping valves causing a corresponding change of a total cross-section area available for producing said multi-phase fluid from said petroleum well.
