Apparatus and method for lubricating and injecting downhole equipment into a wellbore

Abstract

An apparatus and method for lubricating and injecting downhole equipment into a wellbore includes a blowout preventer, a spool for enclosing the downhole equipment, a pressure isolation window, and a hydraulic cylinder. The blowout preventer is positioned above a wellhead. The spool is positioned above the blowout preventer. The pressure isolation window is positioned above the spool. The hydraulic cylinder is positioned above the pressure isolation window. The hydraulic cylinder comprises a rod connected to the downhole equipment, and the hydraulic cylinder is used to lower the downhole equipment into the wellbore.

1 . An apparatus for lubricating and injecting downhole equipment into a wellbore comprising:
 a spool for enclosing the downhole equipment;   a blowout preventer positioned below the spool;   a pressure isolation window positioned above the spool, wherein the pressure isolation window comprises a lower packing gland and an upper packing gland; and   a hydraulic cylinder positioned above the pressure isolation window, wherein the hydraulic cylinder comprises a rod connected to the downhole equipment.   
   
   
       2 . The apparatus of  claim 1 , wherein the blowout preventer comprises internal rams. 
   
   
       3 . The apparatus of  claim 1 , wherein the spool comprises a plurality of spool segments. 
   
   
       4 . The apparatus of  claim 1 , wherein the pressure isolation window further comprises a base connected to the lower packing gland, a top connected to the upper packing gland, and a support. 
   
   
       5 . The apparatus of  claim 1 , wherein the lower packing gland and the upper packing gland each comprises a packing gland body, a packing gland nut that engages the packing gland body, V-packing, and a packing gland pusher. 
   
   
       6 . The apparatus of  claim 1 , wherein the lower packing gland further comprises a ring seal. 
   
   
       7 . The apparatus of  claim 1 , wherein the rod is connected to the downhole equipment via a connector sub. 
   
   
       8 . The apparatus of  claim 1 , wherein the rod comprises modular rod segments. 
   
   
       9 . A method for lubricating and injecting downhole equipment into a wellbore comprising the steps of:
 positioning a blowout preventer above a wellhead;   positioning a spool above the blowout preventer;   assembling the downhole equipment in the spool;   positioning a pressure isolation window above the spool, wherein the pressure isolation window comprises a lower packing gland and an upper packing gland;   positioning a hydraulic cylinder above the pressure isolation window, wherein the hydraulic cylinder comprises a rod connected to the downhole equipment.   
   
   
       10 . The method in accordance with  claim 9 , wherein the blowout preventer is connected to the lower end of the spool. 
   
   
       11 . The method in accordance with  claim 9 , wherein the blowout preventer comprises internal rams. 
   
   
       12 . The method in accordance with  claim 9 , wherein the pressure isolation window is attached to the upper end of the spool. 
   
   
       13 . The method of  claim 12 , wherein the spool comprises a plurality of spool segments that are subsequently attached in order to enclose the downhole equipment as it is being assembled. 
   
   
       14 . The method in accordance with  claim 9 , wherein the spool comprises a plurality of spool segments. 
   
   
       15 . The method in accordance with  claim 9 , wherein the pressure isolation connector further comprises a base connected to the lower packing gland, a top connected to the upper packing gland, and a support. 
   
   
       16 . The method in accordance with  claim 9 , wherein the lower packing gland and upper packing gland each comprise a packing gland body, a packing gland nut that engages the packing gland body, V-packing, and a packing gland pusher. 
   
   
       17 . The method in accordance with  claim 9  wherein the lower packing gland further comprises a ring seal. 
   
   
       18 . The method in accordance with  claim 9  wherein the rod is connected to the downhole equipment via a connector sub. 
   
   
       19 . The method in accordance with  claim 9 , wherein the rod comprises modular rod segments.
