ACTUATOR CONTROLLED VARIABLE FLOW AREA STATOR FOR FLOW SPLITTING IN DOWN-HOLE TOOLS

摘要

Systems and methods divide flow in a wellbore into a plurality of flow paths. A first one of the flow paths extends to a down-hole turbine that is responsive to fluid flow to provide rotational motion to an electric generator or other down-hole tool. A second flow path may extend to an independent down-hole tool, to a port communicating with the wellbore, to a bypass channel extending around the turbine, or to any other down-hole location. The turbine includes a stator having adjustable blades such that an open flow area through the turbine may be selectively controlled. A flow distribution between the first and second flow paths can be controlled where specific flow areas are needed at specific flow rates, for example.
