Casing alignment tool

Abstract

A casing alignment tool detachably mounts on a wellhead flange for moving a section of a casing into a concentric alignment with the wellhead of a well bore. The tool has a base plate attachable to the flange and a perpendicularly extending back plate, which supports a hydraulic jack or a winch. In the embodiment having a hydraulic jack, the tool provides for a V-block assembly with spread arms for pushing against the casing when the hydraulic jack is operated. In the embodiment using a winch, one or more flexible, non-stretchable bands are provided for wrapping around the casing and pulling the casing into alignment, with the flange acting as a fulcrum.

       21 . A tool assembly for positioning an inner tubular member in a desired position within an outer tubular assembly, comprising: 
 a baseplate adapted to be secured to the outer tubular assembly;    an actuator connected to said baseplate; and    a power source connected to said actuator and providing energy for said actuator, wherein said actuator is positioned to exert a force against the inner tubular member to move the inner tubular member into the desired position.    
   
   
       22 . The tool assembly of  claim 21 , further comprising a support shoe attached to said actuator, said support shoe adapted to contact the inner tubular member.  
   
   
       23 . The tool assembly of  claim 21 , further comprising a frame secured to said baseplate, wherein said actuator is coupled to said frame.
