Well Casing Perforator Tool

Abstract

A perforator tool that offers a simple solution to create multiple perforations at different lengths and locations inside a well casing. The perforator tool includes a tool housing that holds all of the components together along with providing a means of connecting the perforator tool to the drill pipe, and a means of transferring pressurized fluid from the drill pipe to use to engage the knife into the well casing, a knife that is used to create the perforation puncture(s) inside the well casing, a pin to hold and allow the knife to pivot inside the tool housing, and a spring connected to a set screw to be able to adjust the spring force to disengage the knife from the well casing.

1 . A perforator tool  1  mounted to a drill pipe  9  and is used to create perforation puncture(s)  8 . 1  inside a well casing  8 , comprising:
 A tool housing  2 , in which said tool housing  2  internally contains a knife chamber  2 . 1 , a fluid channel  2 . 2 , a threaded rod connection  2 . 3 , and a threaded spring enclosure  2 . 4 , a knife  3  for creating said perforation punctures  8 . 1  into said well casing  8 , a pin  4  to hold said knife  3  inside said knife chamber  2 . 1 , a spring  5  to disengage said knife  3  into said knife chamber  2 . 1  around said pin  4 , and a set screw  6  to adjust said spring  5  force inside said threaded spring enclosure  2 . 4 . 
 
     
     
         2 . A method for perforating a well casing  8  with a perforator tool  1  comprising:
 Threading on said perforating tool  1  onto a drill pipe  9  and lowering said perforator tool  1  into said well casing  8 , via said drill pipe  9 , to a perforator puncture  8 . 1  location inside said well casing  8 , engaging a knife  3  housed inside said perforator tool  1  into said well casing  8  by a fluid  10  that is supplied by said drill pipe  9  and a series of housings  2 ,  2 . 1 ,  2 . 2 , and  2 . 3  inside said perforator tool  1 , where a spring  5  along with a set screw  6  and a pin  4  located internally to said perforator tool housing  2  disengages said knife  3  from said well casing  8  to be able to complete multiple said perforator punctures  8 . 1  into said well casing  8 .
