Downhole clamp system

Abstract

A downhole clamp system includes a first clamp member having a first body having a first outer surface and a first inner annular surface configured to engage a downhole tubular. One or more lugs extend radially outwardly from the first outer surface, and a first clamping finger extends radially outwardly from the first outer surface. A second clamp member is arranged adjacent to the first clamp member. The second clamp member includes a second body having a second outer surface and a second inner annular surface configured to engage a downhole tubular. One or more lugs extend radially outwardly from the second outer surface, and a second clamping finger extends radially outwardly from the second outer surface.

         8 . The downhole clamp member according to  claim 7 , wherein one or more of the one or more lugs includes a threaded passage. 
     
     
         9 . The downhole clamp member according to  claim 8 , wherein another of the one or more lugs includes a recess configured and disposed to receive a head portion of a mechanical fastener. 
     
     
         10 . The downhole clamp member according to  claim 7 , wherein the inner annular surface includes one or more recesses configured and disposed to receive a projection extending radially outwardly of an outer surface of a downhole tubular. 
     
     
         11 . The downhole clamp member according to  claim 7 , further comprising a clamping ring configured and disposed to be arranged between adjacent clamp members, the clamping ring being configured and disposed to prevent rotational and axial movement of the first and second clamp members relative to a downhole tubular. 
     
     
         12 . The downhole clamp member according to  claim 11 , wherein the clamping ring includes a first axially outwardly facing surface and an opposing, second axially outwardly facing surface, each of the first and second axially outwardly facing surfaces including a tapered section. 
     
     
         13 . The downhole clamp member according to  claim 7 , wherein the clamping finger is configured and disposed to retain a cable to an outer surface of the downhole tubular. 
     
     
         14 . A resource extraction and recovery system comprising:
 a surface portion including at least one pump;   a downhole portion including a downhole tubular having an outer surface;   a first clamp member including a first body having a first outer surface and a first inner annular surface extending about the outer surface of the downhole tubular, one or more lugs extending radially outwardly from the first outer surface, and a first clamping finger extending radially outwardly from the first outer surface;   a second clamp member arranged adjacent to the first clamp member, the second clamp member including a second body having a second outer surface and a second inner annular surface extending about the outer surface of the downhole tubular, one or more lugs extending radially outwardly from the second outer surface, and a second clamping finger extending radially outwardly from the second outer surface, each of the one or more lugs being operatively engaged with a corresponding one of each of the one or more lugs to join the first clamp member and the second clamp member.   
     
     
         15 . The resource extraction and recovery system according to  claim 14 , wherein one or more of the one or more lugs includes a threaded passage.
