Quick connect device for fractrap and method

Abstract

A quick connect device for connecting a plug to a setting tool includes a collet having a body and plural fingers; a first end of the collet is configured to be attached to a trapping mechanism associated with the setting tool; and a second end of the collet has the plural fingers, which are configured to be attached to the plug. The second end automatically connects to the plug by only pushing the second end onto the plug.

What is claimed is: 
     
         1 . A quick connect device for connecting a plug to a setting tool, the quick connect device comprising:
 a collet having a body and plural fingers;   a first end of the collet is configured to be attached to a trapping mechanism associated with the setting tool; and   a second end of the collet has the plural fingers, which are configured to be attached to the plug,   wherein the second end automatically connects to the plug by only pushing the second end onto the plug.   
     
     
         2 . The quick connect device of  claim 1 , wherein each finger of the plural fingers engages a ring located on the plug. 
     
     
         3 . The quick connect device of  claim 2 , wherein each finger has a tab which is configured to move past the ring and lock the tab onto the ring. 
     
     
         4 . The quick connect device of  claim 3 , wherein at least one finger of the plural fingers has an extension that extends past the corresponding tab. 
     
     
         5 . The quick connect device of  claim 2 , wherein at least one finger of the plural fingers is longer than the plural fingers. 
     
     
         6 . The quick connect device of  claim 1 , wherein the collet is attached with threads to the trapping mechanism. 
     
     
         7 . The quick connect device of  claim 6 , wherein the trapping mechanism is attached with threads to the internal sleeve of the setting tool. 
     
     
         8 . The quick connect device of  claim 1 , wherein the collet, the trapping mechanism, and the plug fluidly communicate with each other and a ball is sized to pass through the collet, from the plug to the trapping mechanism. 
     
     
         9 . The quick connect device of  claim 8 , further comprising:
 the ball, wherein the ball is sized to not pass through an internal bore of the plug and the trapping mechanism is configured to trap the ball to prevent the ball from returning to the plug.   
     
     
         10 . A system for connecting a plug to a setting tool with a quick connect device, the system comprising:
 the plug, which is configured to seal a bore of a casing in a well; and   the quick connect device,   wherein the quick connect device has a collet that automatically engages and locks onto the plug by only pushing the collet onto the plug.   
     
     
         11 . The system of  claim 10 , further comprising:
 a trapping mechanism configured to be attached to an internal sleeve of the setting tool; and   an external sleeve configured to house the trapping mechanism and the quick connect device,   wherein the collet is configured to be attached with a first end to the trapping mechanism and with a second end to the plug.   
     
     
         12 . The system of  claim 10 , wherein the plug has a mandrel and a ring located on the mandrel. 
     
     
         13 . The system of  claim 12 , wherein the collet has plural fingers at the second end, and each finger engages the ring located on the mandrel. 
     
     
         14 . The system of  claim 13 , wherein each finger has a tab which is configured to move past the ring and lock the tab onto the ring. 
     
     
         15 . The system of  claim 12 , wherein the ring is configured to break at a desired force, to free the quick connect device from the plug. 
     
     
         16 . The system of  claim 12 , wherein the ring is molded into a mandrel of the plug. 
     
     
         17 . The system of  claim 12 , wherein the ring is placed into a trench formed in a mandrel of the plug. 
     
     
         18 . The system of  claim 13 , wherein at least one finger of the plural fingers has an extension that extends past the corresponding tab. 
     
     
         19 . The system of  claim 11 , further comprising:
 a ball, wherein the trapping mechanism has an internal chamber configured to hold the ball and the ball is sized to pass through an internal bore of the collet.   
     
     
         20 . A method for connecting a plug to a setting tool before being deployed in a well, the method comprising:
 providing a plug having a mandrel, the mandrel having a ring that extends around and away from the mandrel;   attaching a trapping mechanism to a collet;   attaching the collet to the ring of the plug by only pushing the collet onto the plug;   sliding the trapping mechanism, while connected to the collet and the plug, inside an external sleeve of a setting kit; and   rotating the plug to attach threads of the trapping mechanism to an internal sleeve of the setting tool.
