US 2014/0174746 A1 · SLEEVE VALVE

Abstract

An sleeve valve for a well assembly includes at least one set of passages extending through a tubular body between the central passage and an exterior of the tubular body and a sleeve slidably located within the central passage of the valve body adapted to selectably sealably cover or uncover the at least one sets of passages. A shifting tool for actuating the sleeve valve is connectable to a tool string and includes a shifting bore with an actuating piston extending from a central bore through the shifting tool and first and second key bores extending radially inwards from the outer surface each having a piston keys located therein. Each of the first and second piston keys is operably connected to the actuating piston so as to be extended from the outer surface when the central bore is supplied with a pressurized fluid.

Dependent claims

An apparatus for selectably permitting fluidic communication between an interior and an exterior of a well assembly comprising:

a tubular body extending between first and second ends and having a central passage extending therebetween, said first and second ends being connectable to said well assembly such that said central passage is in fluidic communication with an interior of said well assembly;
at least one set of passages extending through said tubular body between said central passage and an exterior of said tubular body;
a sleeve slidably located within said central passage of said valve body adapted to selectably sealably cover or uncover said at least one sets of passages;
and
a shifting tool slidably locatable within said sleeve at an end of a tool string said shifting tool being engagable upon said sleeve so as to permit said shifting tool to move said sleeve longitudinally within said tubular body.
