Liner setting tool

Abstract

A liner setting tool. A system for conveying a liner string into a subterranean well includes a liner setting tool which selectively connects and disconnects a work string and a liner string. The liner setting tool is configured to transmit compressive force, tensile force and torque between the work string and the liner string. In another system, the liner setting tool is operable to disconnect the work string from the liner string in response to a predetermined pressure differential applied to the liner setting tool. In yet another system, the liner setting tool is operable to disconnect the work string from the liner string in response to displacement of a release member of the liner setting tool followed by displacement of the work string relative to the liner string.

1 . A system for conveying a liner string into a subterranean well, the system comprising: 
 a liner setting tool which selectively connects and disconnects a work string and the liner string, the liner setting tool being configured to transmit each of a compressive force, a tensile force and a torque between the work string and the liner string.    
   
   
       2 . The system of  claim 1 , wherein the liner setting tool disconnects the work string from the liner string in response to displacement of a release member of the liner setting tool.  
   
   
       3 . The system of  claim 2 , wherein the liner setting tool disconnects the work string from the liner string further in response to displacing the work string toward the liner string after displacement of the release member.  
   
   
       4 . The system of  claim 2 , wherein the release member displaces in response to application of a predetermined pressure differential to the liner setting tool.  
   
   
       5 . The system of  claim 4 , wherein the liner setting tool includes a flow passage, installation of a plug in the flow passage permitting the pressure differential to be applied to the liner setting tool.  
   
   
       6 . The system of  claim 4 , wherein the pressure differential is relieved upon displacement of the release member.  
   
   
       7 . The system of  claim 2 , wherein the liner setting tool continues to transmit the tensile force and torque between the work string and the liner string after displacement of the release member.  
   
   
       8 . A system for conveying a liner string into a subterranean well, the system comprising: 
 a liner setting tool which selectively connects and disconnects a work string and the liner string, the liner setting tool being operable to disconnect the work string from the liner string in response to a predetermined pressure differential applied to the liner setting tool.    
   
   
       9 . The system of  claim 8 , wherein the liner setting tool is further operable to disconnect the work string from the liner string in response to application of a predetermined force to the liner setting tool.  
   
   
       10 . The system of  claim 8 , wherein the liner setting tool is configured to transmit each of a compressive force, a tensile force and a torque between the work string and the liner string.  
   
   
       11 . The system of  claim 8 , wherein a release member of the liner setting tool displaces in response to application of the predetermined pressure differential to the liner setting tool.  
   
   
       12 . The system of  claim 11 , wherein the liner setting tool disconnects the work string from the liner string further in response to displacing the work string toward the liner string after displacement of the release member.  
   
   
       13 . The system of  claim 11 , wherein the pressure differential is relieved upon displacement of the release member.  
   
   
       14 . The system of  claim 11 , wherein the liner setting tool continues to transmit tensile force and torque between the work string and the liner string after displacement of the release member.  
   
   
       15 . A system for conveying a liner string into a subterranean well, the system comprising: 
 a liner setting tool which selectively connects and disconnects a work string and the liner string, the liner setting tool being operable to disconnect the work string from the liner string in response to displacement of a release member of the liner setting tool followed by displacement of the work string toward the liner string.    
   
   
       16 . The system of  claim 15 , wherein the liner setting tool is configured to transmit each of a compressive force, a tensile force and a torque between the work string and the liner string.  
   
   
       17 . The system of  claim 16 , wherein the liner setting tool continues to transmit the tensile force and torque between the work string and the liner string after displacement of the release member.  
   
   
       18 . The system of  claim 15 , wherein the release member displaces in response to application of a predetermined pressure differential to the liner setting tool.  
   
   
       19 . The system of  claim 18 , wherein the pressure differential is relieved upon displacement of the release member.  
   
   
       20 . The system of  claim 15 , wherein the release member displaces in response to application of a predetermined force to the liner setting tool.
