Wear resistant drill pipe

Abstract

Embodiments relate generally to preventing wear to a nominal thickness of a wall of a drill pipe during a downhole operation. A drill pipe may include a first tool joint; a second tool joint; and a tubular section between the first tool joint and the second tool joint, wherein the tubular section comprises a wall with an overall thickness comprising a nominal thickness and a secondary thickness, wherein the secondary thickness is outer to the nominal thickness and is configured to abrade against a wall of the wellbore, thereby reducing the secondary thickness and maintaining the nominal thickness, wherein an ID of each tool joint is less than an ID of the tubular section to accommodate for threaded connectors.

What is claimed is: 
     
         1 . A drill pipe comprising:
 a first tool joint;   a second tool joint; and   a tubular section between the first tool joint and the second tool joint, wherein the tubular section comprises a wall with an overall thickness comprising a nominal thickness and a secondary thickness, wherein the secondary thickness is outer to the nominal thickness and is configured to abrade against a wall of a wellbore, thereby reducing the secondary thickness and maintaining the nominal thickness, wherein an ID of each tool joint is less than an ID of the tubular section to accommodate for threaded connectors.   
     
     
         2 . The drill pipe of  claim 1 , wherein the drill pipe is positioned in a vertical section of the wellbore. 
     
     
         3 . The drill pipe of  claim 1 , wherein the secondary thickness is at least 10% of the nominal thickness. 
     
     
         4 . The drill pipe of  claim 3 , wherein a weight per length of the drill pipe is less than a weight per length of a heavy weight drill pipe having a similar outer diameter (OD) to that of the drill pipe. 
     
     
         5 . The drill pipe of  claim 4 , wherein the drill pipe is positioned in a horizontal section of the wellbore. 
     
     
         6 . The drill pipe of  claim 4 , wherein the drill pipe is positioned in a section of the wellbore that deviates from a vertical direction by 45 degrees to 90 degrees. 
     
     
         7 . The drill pipe of  claim 6 , wherein the nominal thickness is not exposed to the wall of the wellbore. 
     
     
         8 . The drill pipe of  claim 5 , wherein the drill pipe does not contain mid-tube welds. 
     
     
         9 . A drill pipe comprising:
 a first tool joint;   a second tool joint; and   a tubular section between the first tool joint and the second tool joint, wherein the tubular section comprises a wall with an overall thickness comprising a nominal thickness and a secondary thickness,   wherein the secondary thickness is outer to the nominal thickness,   wherein the tubular section does not contain mid-tube welds,   wherein a weight per length of the drill pipe is less than a weight per length of a heavy weight drill pipe having a similar outer diameter to that of the drill pipe.   
     
     
         10 . The drill pipe of  claim 9 , wherein the drill pipe is positioned in a section of a wellbore that deviates from a vertical direction by 45 degrees to 90 degrees. 
     
     
         11 . The drill pipe of  claim 9 , wherein the drill pipe is positioned in a horizontal section of a wellbore. 
     
     
         12 . The drill pipe of  claim 9 , wherein the secondary thickness is at least 10% of the nominal thickness. 
     
     
         13 . The drill pipe of  claim 9 , wherein the secondary thickness is configured to abrade against the wall of a wellbore, thereby reducing the secondary thickness. 
     
     
         14 . The drill pipe of  claim 13 , wherein the nominal thickness is configured to not abrade against the wall of the wellbore due the secondary thickness preventing contact between the wall of the wellbore and the nominal thickness. 
     
     
         15 . The drill pipe of  claim 9 , wherein an inner diameter (ID) of the tubular section is uniform. 
     
     
         16 . The drill pipe of  claim 15 , wherein an ID of each tool joint is less than an ID of the tubular section to accommodate for threaded connectors. 
     
     
         17 . A method for preventing a reduction in a nominal thickness of a drill pipe, the method comprising:
 positioning the drill pipe in a wellbore, wherein a wall of the drill pipe comprises an overall thickness comprising the nominal thickness and a secondary thickness, wherein the secondary thickness is outer to the nominal thickness;   manipulating the drill pipe in the wellbore, causing the drill pipe's outer surface to contact a wall of the wellbore;   reducing the secondary thickness due to abrasive forces between the wall of the wellbore and the drill pipe; and   maintaining the nominal thickness.   
     
     
         18 . The method of  claim 17 , wherein the secondary thickness is at least 10% of the nominal thickness. 
     
     
         19 . The method of  claim 18 , wherein the drill pipe does not contain mid-tube welds. 
     
     
         20 . The method of  claim 19 , wherein a weight per length of the drill pipe is less than a weight per length of a heavy weight drill pipe having a similar outer diameter (OD) to that of the drill pipe.
