Submersible pump systems and methods

摘要

A submersible pump system that is operable to permit selective access into a production zone of a well bore while a submersible pumping device is operating includes a Y-tool, a submersible pumping device, a control valve assembly and a power conduit. The control valve assembly is also operable to selectively permit access between the interior of the submersible pumping system and the exterior of the submersible pumping system. The valve is operable to form a dynamic seal. The power conduit is operable to convey both power and a pre-designated control signal simultaneously. A method for accessing the production zone of the well bore with a well bore tool uses the submersible pump system while the submersible pump system is producing production zone fluid. The submersible pumping device continues to operate without interruption after transmission of the pre-designated pump control signal.

主权项

1. A submersible pump system that is operable to permit selective access into a production zone of a well bore while a submersible pumping device is operating, the submersible pump system comprising:
a Y-tool having a production tubing branch, a submersible pump branch and a bypass branch; a submersible pumping device that couples to and is in fluid communication with the Y-tool through the submersible pump branch, where the submersible pumping device is operable to receive a pre-designated pump control signal; a control valve assembly that couples to and is in fluid communication with the Y-tool through the bypass branch, where the control valve assembly comprises a valve, is operable to receive a pre-designated valve control signal and is operable to selectively permit access between the interior of the submersible pumping system and the exterior of the submersible pumping system, and where the valve comprises both a valve disk and a valve bore wall, where the valve bore wall defines a valve bore; a seal assembly in the control valve assembly that dynamically seals against an outer surface of a well bore tool that selectively is inserted through the control valve assembly; and a power conduit that couples to and is in communication with both the submersible pumping device and the control valve assembly, where the power conduit is operable to convey both power and a pre-designated control signal simultaneously.
