System, method, and device for actuating a downhole tool

Abstract

An actuating component for a downhole tool is provided that includes a main actuating bore and an actuating liner configured to be accommodated within the main actuating bore. The actuating component may further include a piston configured to sealingly and translatably fit within the actuating liner and be coupled to the downhole tool wherein movement of the piston relative to the actuating liner actuates the downhole tool. A method of actuating a downhole tool is also provide that may include installing an actuating liner within a main actuating bore and providing a piston configured to translatably and sealably be accommodated within the actuating liner. The method may further comprise coupling the piston to an operative component of the downhole tool and applying pressure to a surface of the piston, thereby moving the piston relative to the actuating liner.

 a main actuating bore,   an actuating liner configured to be accommodated within the main actuating bore;   a piston configured to sealingly and translatably fit within the actuating liner and coupled to the downhole tool; and   wherein movement of the piston relative to the actuating liner actuates the downhole tool.   
     
     
         2 . The actuating component as recited in  claim 1 , in which the actuating liner is threadably coupled to the main actuating bore. 
     
     
         3 . The actuating component as recited in  claim 1 , in which the actuating liner is adhered to the main actuating bore. 
     
     
         4 . The actuating component as recited in  claim 1 , in which the actuating liner is press fit into the main actuating bore. 
     
     
         5 . The actuating component as recited in  claim 1 , in which the actuating liner comprises Inconel 718. 
     
     
         6 . The actuating component as recited in  claim 1 , in which the downhole tool is a valve. 
     
     
         7 . The actuating component as recited in  claim 1 , in which the main actuating bore comprises a first material; and
 the actuating liner comprises a second material not identical in composition to the first material.   
     
     
         8 . The actuating component as recited in  claim 7 , in which the second material comprises a higher cost per pound than the first material. 
     
     
         9 . The actuating component as recited in  claim 7 , in which the second material comprises a higher corrosion resistance than the first material. 
     
     
         10 . A system for actuating a downhole tool comprising:
 a source of hydraulic pressure;   a main actuating bore;   an actuating liner configured to be accommodated within the main actuating bore;   a piston ultimately coupled to an operative component of a downhole tool and configured to sealingly and translatably fit within the actuating liner; and   wherein the source of hydraulic pressure is applied to at least one surface of the piston resulting in translation of the piston relative to the actuating liner; and   wherein the translation of the piston relative to the actuating liner corresponds to movement of the operative component of the downhole tool.   
     
     
         11 . The system recited in  claim 10  wherein the main actuating bore comprises a first material; and
 the actuating liner comprises a second material. 
 
     
     
         12 . The system recited in  claim 11  wherein the second material has a higher degree of corrosion resistance than the first material. 
     
     
         13 . The system recited in  claim 10  wherein the source of hydraulic pressure is supplied via a hydraulic pump located downhole. 
     
     
         14 . The system recited in  claim 10  wherein the actuating liner is threadably coupled to the main actuating bore. 
     
     
         15 . The system recited in  claim 10  wherein the actuating liner is adhered to the main actuating bore. 
     
     
         16 . A method of actuating a downhole tool comprising:
 installing an actuating liner within a main actuating bore;   providing a piston configured to translatably and sealably be accommodated within the actuating liner;   coupling the piston to an operative component of the downhole tool; and   applying pressure to a surface of the piston, thereby moving the piston relative to the actuating liner;   wherein the movement of the piston relative to the actuating liner actuates the downhole tool via corresponding movement of the operative component.   
     
     
         17 . The method as recited in  claim 16 , wherein the main actuating bore comprises a first material; and
 the actuating liner comprises a second material.   
     
     
         18 . The method as recited in  claim 17 , wherein the second material comprises a higher degree of corrosion resistance than the first material. 
     
     
         19 . The method as recited in  claim 17 , wherein the second material comprises a greater cost per pound than the first material. 
     
     
         20 . The method as recited in  claim 16 , wherein the actuating liner is adhered to the main actuating bore.
