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 first opening; and a second component within the tubing, the second component having a second opening and being rotationally adjustable (i) while in the wellbore only by an intervening tool introduced in the tubing from a surface of the wellbore to rotate the second component mechanically and (ii) among a plurality of physical positions with respect to the first opening for changing resistivity to fluid flow through a flow path through the first opening and the second opening, the flow path including a first component flow path in fluid communication with the first opening and a second component flow path in fluid communication with the second opening, wherein the second component is configured for being adjustable among the plurality of physical positions with respect to the first component for changing resistivity to fluid flow through the flow control assembly by changing a location of the second component flow path with respect to the first component flow path and changing a position of protrusions positioned in part of the flow path, wherein the first component is one of an inner sleeve or an outer sleeve and the second component is the other one of the inner sleeve or the outer sleeve.
