Wellbore Strings Containing Annular Flow Valves

摘要

In one aspect, an apparatus for use in a wellbore is disclosed that in one non-limiting embodiment contains a flow control device for use in a wellbore that includes a bore that provides a first flow path, a second flow path via an annulus around the first flow path, a closing device that closes the second flow path when the closing device is mechanically moved in a first direction and an opening device that opens the second flow path when a fluid under pressure is supplied to the annulus when the valve is closed.

主权项

1. A flow control device for use in a wellbore, comprising:
a first flow path providing a flow path for a first fluid from a first production zone; a second flow path in an annulus around the first flow path providing a flow path for a second fluid from a second production zone; a first device that in a first position opens the second flow path and in a second position closes the second flow path; and a second device that moves the first device from the second position to the first position when hydraulic pressure is applied to the annulus to open the second flow path.
