Apparatus for downhole water production control in an oil well

摘要

This invention relates to controlling production fluids downhole in an oil well. More specifically, this invention relates to control of water and pressure downhole. Provided are apparatus for controlling production fluids and pressures and methods of using the apparatus to control production fluids and pressures.

主权项

1. An apparatus capable of controlling pressure and production fluids in a circular pipe in a downhole region of a well bore, the apparatus comprising:
the circular pipe comprising at least one pipe orifice on a lower side of the circular pipe, the pipe orifice operable to allow the flow of production fluids through the orifice into the circular pipe; an inclined wall within the circular pipe, the inclined wall having a plurality of flow control members positioned at different horizontal levels relative to the inclined wall; the flow control members each having a housing with an inner chamber and a buoyant element within the inner chamber of the housing, such that the buoyant element moves vertically within the inner chamber relative to a density of the production fluids; each housing having a lower housing orifice and an upper housing orifice; and a space located between the pipe orifice and the inclined wall.
