Expandable tubular thread protection

Abstract

Herein disclosed is a method of protecting a tubular or a component attached to the tubular, comprising making two sections of the expandable tubular into two complete centralizing rings or two partial centralizing rings having a larger outer diameter than the remainder of the expandable tubular, wherein the two complete centralizing rings or partial centralizing rings are on two ends of the component. Also discussed herein is an assembly comprising an expandable tubular, a component attached to the tubular, a sleeve over the component and an adhesive; wherein the adhesive fully covers the space between the inside diameter of the sleeve and the outside diameter of the component. The sleeve remains in place when the tubular is placed down hole. Related methods and assemblies are discussed in further details.

What is claimed is: 
     
         1 . A method of protecting a tubular or a component attached to the tubular, comprising
 making two sections of the expandable tubular into two complete centralizing rings or two partial centralizing rings having a larger outer diameter than the remainder of the expandable tubular, wherein said two complete centralizing rings or partial centralizing rings are on two ends of said component.   
     
     
         2 . The method of  claim 1 , wherein the component includes a box thread. 
     
     
         3 . The method of  claim 1 , wherein the outer diameter of the two complete or partial centralizing rings is larger than or equal to the outer diameter of the component attached to the tubular. 
     
     
         4 . The method of  claim 1 , wherein said tubular comprises a casing, a liner, a screen, or a production tubing. 
     
     
         5 . The method of  claim 1  furthering comprising placing a sleeve between the two complete or partial centralizing rings and over the component. 
     
     
         6 . The method of  claim 5  wherein the sleeve is a steel sleeve. 
     
     
         7 . The method of  claim 5  wherein the sleeve is held in place by the two complete or partial centralizing rings to protect the component. 
     
     
         8 . An assembly comprising
 an expandable tubular and a component attached to the tubular;   two sections of the expandable tubular having a larger outer diameter than the remainder of the expandable tubular, forming two complete centralizing rings or two partial centralizing rings, wherein said two complete centralizing rings or partial centralizing rings are on two ends of said component.   
     
     
         9 . The assembly of  claim 8  wherein the outer diameter of the two complete or partial centralizing rings is larger than or equal to the outer diameter of the component attached to the tubular. 
     
     
         10 . The assembly of  claim 8  wherein the component includes a box thread. 
     
     
         11 . The assembly of  claim 8  further comprising a sleeve placed between the two complete or partial centralizing rings and over the component. 
     
     
         12 . The assembly of  claim 11  wherein the sleeve is held in place by the two complete or partial centralizing rings to protect the component. 
     
     
         13 . A method of protecting a component attached to an expandable tubular, comprising
 placing a sleeve over the component, wherein said sleeve comprises an input port and at least two tell holes;   applying an adhesive through the input port to fill the space between the inside diameter of the sleeve and the outside diameter of the component until the adhesive comes out of the at least two tell holes.   
     
     
         14 . The method of  claim 13  wherein the adhesive fully covers the space between the inside diameter of the sleeve and the outside diameter of the component such that the sleeve remains in place when the tubular is placed down hole. 
     
     
         15 . The method of  claim 13  further comprising making two sections of the expandable tubular into two complete centralizing rings or two partial centralizing rings having a larger outer diameter than the remainder of the expandable tubular, wherein said two complete centralizing rings or partial centralizing rings are on two ends of said component and sleeve. 
     
     
         16 . The method of  claim 13  wherein applying the adhesive comprises using a pump, a mixing tube, and a sealed input cap. 
     
     
         17 . The method of  claim 16  wherein said pump includes a plural component pump. 
     
     
         18 . An assembly comprising
 an expandable tubular, a component attached to the tubular, a sleeve over the component and an adhesive; wherein said adhesive fully covers the space between the inside diameter of the sleeve and the outside diameter of the component.   
     
     
         19 . The assembly of  claim 18  wherein the sleeve remains in place when the tubular is placed down hole. 
     
     
         20 . The assembly of  claim 18  further comprising two sections of the expandable tubular having a larger outer diameter than the remainder of the expandable tubular, forming two complete centralizing rings or two partial centralizing rings, wherein said two complete centralizing rings or partial centralizing rings are on two ends of said component and sleeve.
