Mechanically adjustable flow control assembly

摘要

A flow control assembly can be mechanically adjusted, rotationally or translationally, inside a tubing downhole between multiple positions by an intervening tool from the surface to change resistivity to flow through the flow control assembly. The positions among which the flow control assembly can be adjusted can include a closed position, a fully open position, and positions at which fluid experiences various resistances prior to flowing to an inner area of the tubing.

主权项

1. A flow control assembly configured for being disposed with tubing in a wellbore, the flow control assembly comprising:
a first component having a plurality of first openings longitudinally spaced with respect to each other; a second component within the tubing, the second component having a second opening and being mechanically and translationally adjustable (i) while in the wellbore by an intervening tool introduced in the tubing from a surface of the wellbore and (ii) among a plurality of physical positions with respect to the plurality of first openings for changing resistivity to fluid flow through a flow path through the second opening and at least one first opening of the plurality of first openings; and a flow restrictor in the flow path between a housing and at least one of the plurality of first openings, the flow restrictor being unaligned with respect to the plurality of first openings.
