Packer Bridge Plug with Slips

Abstract

The present invention is to a packer plug that can be tripped into a particular location in a well bore and set using slips rings and packer elements. The plug presents little flow resistance because of its wide inner diameter throat through the mandrel. A ball seat at an upper end allows for the sealing of the interior passage. The ball can be flowed upward or dissolved to remove the seal and allow flow through the plug. A slip ring can be used in place of slips to reduce the overall length of the packer plug.

I claim: 
     
         1 . A bridge plug for sealing a well bore comprising:
 a mandrel having a tubular body and a collet;   a ball seat at an upper end for receiving a ball to seal flow through the mandrel body;   a packer element mounted to the mandrel for selectively sealing flow outside the mandrel body;   an upper conical body slidably mounted on the mandrel and a lower conical body mounted on the mandrel;   at least one slip ring mounted between the upper conical body and lower sub causing the slip to expand away the mandrel when the slip slides over the upper conical body.   
     
     
         2 . The bridge plug of  claim 1  wherein the slip ring is a narrow band of material having a precut section to allow the band to expand radially. 
     
     
         3 . The bridge plug of  claim 1  wherein the slip ring is a narrow band of material having an expandable section to allow the band to expand radially.  
     
     
         4 . The bridge plug of  claim 1  wherein the slip ring is a C shaped hoop of material having frictional elements mounted about an outer circumference of the hoop. 
     
     
         5 . The bridge plug of  claim 1  wherein the slip ring is a C shaped hoop of material having frictional elements mounted about an outer circumference of the hoop, wherein the frictional elements are made of carbide.
