Connector for use in a wellbore

Abstract

A method and apparatus for connecting a component to a rod for use in downhole operations. Wherein the method and apparatus is design to reduce stress and the risk of failures in the connection during downhole operations. The method and apparatus having a connector assembly that is designed with only two wrench flats in order to minimize stress concentrations during operation. The method and apparatus having an optional intermediate alloy metallurgy.

1 . A connector for connecting a rod to a wellbore component comprising: 
 a first end for connecting to the component;    a second end for connecting the body to the rod; and    a cross section defining a cylindrical shape with opposing planar portions for engagement with a torquing member.    
   
   
       2 . The apparatus of  claim 1 , where the planar portions are substantially parallel.  
   
   
       3 . The apparatus of  claim 1 , wherein the planar portions are substantially the same distance apart as a diameter of the rod.  
   
   
       4 . The apparatus of  claim 1 , wherein the planar portions are a greater distance apart than a diameter of the rod.  
   
   
       5 . The apparatus of  claim 1 , wherein the first end comprises male threads.  
   
   
       6 . The apparatus of  claim 1 , wherein the second end has a shaft with substantially the same diameter as the rod.  
   
   
       7 . The apparatus of  claim 6 , wherein the shaft has a body end with an enlarged diameter that couples to the body.  
   
   
       8 . The apparatus of  claim 1 , wherein the component is a pump.  
   
   
       9 . The apparatus of  claim 8 , wherein the pump is a progressive cavity pump.  
   
   
       10 . The apparatus of  claim 8 , wherein the pump is a reciprocating pump.  
   
   
       11 . The apparatus of  claim 1 , wherein the component is another rod.  
   
   
       12 . The apparatus of  claim 1 , wherein the rod is a continuous rod.  
   
   
       13 . The apparatus of  claim 1 , wherein the rod is a sucker rod.  
   
   
       14 . A method for connecting a rod to a component for use in a wellbore comprising: 
 providing a connector having a cross section defining a cylindrical shape with opposing planar portions for engagement and a pin end;    engaging the opposing planar portions with a tool;    connecting the component to rotating a shaft of the component while preventing the connector from rotating; and    coupling the rod to the connector.    
   
   
       15 . An apparatus for operating a downhole tool from the surface of a wellbore, comprising: 
 a tool for performing a downhole operation; and    a rod for operating the tool from the surface having an intermediate alloy content.    
   
   
       16 . The apparatus of  claim 15 , wherein the intermediate alloy content is in the range of 2½% Cr. to 13% Cr.  
   
   
       17 . The apparatus of  claim 15 , wherein the intermediate alloy content is approximately 5 Cr½-½Mo.  
   
   
       18 . The apparatus of  claim 17 , wherein the rod is a continuous rod.  
   
   
       19 . The apparatus of  claim 17 , wherein the rod is a sucker rod.
