High pressure D-tube with enhanced through tube access

Abstract

A high pressure D-tube with enhanced through tube access for use in a well system. The well system includes the tube having an interior and a generally D-shaped exterior surface. An inner support structure spans the interior of the tube. The exterior surface may be formed on a single piece of material. The inner support structure may resist deformation of the tube due to pressure applied to the interior and/or exterior surface of the tube. The inner support structure may form at least a portion of the exterior surface of the tube.

1 . A well system, comprising: 
 a tube having an interior and a generally D-shaped exterior surface; and    an inner support structure spanning the interior of the tube.    
   
   
       2 . The well system of  claim 1 , wherein the inner support structure resists deformation of the tube due to exterior pressure applied to the tube.  
   
   
       3 . The well system of  claim 1 , wherein the inner support structure resists deformation of the tube due to interior pressure applied to the tube.  
   
   
       4 . The well system of  claim 1 , wherein the D-shaped exterior surface is formed on a single piece of material.  
   
   
       5 . The well system of  claim 1 , wherein the tube and the inner support structure are integrally formed from a single piece of material.  
   
   
       6 . The well system of  claim 1 , wherein the inner support structure comprises a plate.  
   
   
       7 . The well system of  claim 1 , wherein the inner support structure comprises a tubular structure.  
   
   
       8 . The well system of  claim 1 , wherein the inner support structure comprises a series of individual support structures distributed longitudinally within the tube.  
   
   
       9 . The well system of  claim 1 , wherein the inner support structure forms at least a portion of the exterior surface of the tube.  
   
   
       10 . The well system of  claim 1 , wherein the tube comprises multiple open-sided sections which are attached to the inner support structure to thereby form the generally D-shaped exterior surface.  
   
   
       11 . A well system, comprising: 
 a tube having an interior and a generally D-shaped exterior surface, the exterior surface being formed on a single piece of material; and    an inner support structure within the interior of the tube, the support structure resisting deformation of the tube due to pressure applied to the exterior surface.    
   
   
       12 . The well system of  claim 11 , wherein the tube and the inner support structure are integrally formed from a single piece of material.  
   
   
       13 . The well system of  claim 11 , wherein the inner support structure comprises a plate.  
   
   
       14 . The well system of  claim 11 , wherein the inner support structure comprises a tubular structure.  
   
   
       15 . The well system of  claim 11 , wherein the inner support structure comprises a series of individual support structures distributed longitudinally within the tube.  
   
   
       16 . The well system of  claim 11 , wherein the inner support structure resists deformation of the tube due to interior pressure applied to the tube.  
   
   
       17 . A well system, comprising: 
 a tube having an interior and a generally D-shaped exterior surface; and    an inner support structure resisting deformation of the tube due to pressure applied to the exterior surface, and the inner support structure forming at least a portion of the exterior surface of the tube.    
   
   
       18 . The well system of  claim 17 , wherein the tube comprises multiple open-sided sections which are attached to the inner support structure to thereby form the generally D-shaped exterior surface.  
   
   
       19 . The well system of  claim 17 , wherein the inner support structure comprises a plate.  
   
   
       20 . The well system of  claim 17 , wherein the inner support structure comprises a tubular structure.  
   
   
       21 . The well system of  claim 17 , wherein the inner support structure resists deformation of the tube due to pressure applied to the interior of the tube.
