Thread shear wireline adapter kit and borehole tool setting arrangement and method

Abstract

A thread shear based wireline adapter kit and downhole tool setting arrangement including a downhole tool having an inside diameter flow path extending therethrough after setting of the downhole tool, a wireline adapter kit disposed in the flow path, a member disposed at a downhole end of the downhole tool, the member having a threadform therein, the threadform threaded to the wireline adapter kit, the threadform shearable to release the wireline adapter kit from the downhole tool after setting leaving the flow path open. A method for setting a downhole tool including pulling a wireline adapter kit (WLAK) that is secured to a downhole tool by a threadform, loading the threadform axially to set the tool, further loading the threadform to axially shear the threadform, releasing the WLAK from the downhole tool leaving a flow path through the downhole tool.

What is claimed is: 
     
         1 . A thread shear based wireline adapter kit and downhole tool setting arrangement comprising:
 a downhole tool having an inside diameter flow path extending therethrough after setting of the downhole tool;   a wireline adapter kit disposed in the flow path;   a member disposed at a downhole end of the downhole tool, the member having a threadform therein, the threadform threaded to the wireline adapter kit, the threadform shearable to release the wireline adapter kit from the downhole tool after setting leaving the flow path open.   
     
     
         2 . The arrangement as claimed in  claim 1  wherein the member is a bottom sub of the downhole tool. 
     
     
         3 . The arrangement as claimed in  claim 1  wherein the member is a ring disposed adjacent and downhole of a bottom sub of the downhole tool. 
     
     
         4 . The arrangement as claimed in  claim 1  wherein the threadform is a multistart threadform. 
     
     
         5 . The arrangement as claimed in  claim 4  wherein the multistart threadform is a three start threadform. 
     
     
         6 . The arrangement as claimed in  claim 1  wherein the multistart threadform is a four start threadform. 
     
     
         7 . The arrangement as claimed in  claim 1  wherein the member is constructed of a degradable material. 
     
     
         8 . The arrangement as claimed in  claim 7  wherein the degradable material is a controlled electrolytic metallic material. 
     
     
         9 . A method for setting a downhole tool comprising:
 pulling a wireline adapter kit (WLAK)that is secured to a downhole tool by a threadform;   loading the threadform axially to set the tool;   further loading the threadform to axially shear the threadform;   releasing the WLAK from the downhole tool leaving a flow path through the downhole tool.
