  • Drill pipe protector
    Patent number: 7055631
    Abstract: A drill pipe protector having a tubular sleeve that is attached to a section of drill pipe and resides over the outer diameter of the drill pipe while moving within an associated well casing or well hole. The sleeve has low-friction end pads positioned on the ends of the sleeve to reduce friction between the ends of the sleeve and the end of an adjacent thrust bearing collar used to hold the sleeve in place on the drill pipe.
    Type: Grant
    Filed: March 30, 2004
    Date of Patent: June 6, 2006
    Assignee: Western Well Tool, Inc

  • Drill pipe protector
    Publication number: 20020117337
    Abstract: A drill pipe protector assembly for providing hydraulic lift and improved sliding lubrication to a drill string. The protector defines a tubular sleeve that is attached to a section of drill pipe and resides over the outer diameter of the drill pipe while moving within an associated well casing or well hole. The sleeve is adapted to provide hydraulic lift and sliding lubrication relative to the well casing and thus, increase the proclivity of the drill pipe to slide down the hole while also reducing the development of cutting dams. The sleeve includes a plurality of radially oriented openings which direct drilling mud from the annular space between the sleeve and drill pipe to the annular space between the sleeve and the casing or outer well wall. The sleeve also includes a plurality of wedge shaped longitudinal channels in communication with the radial openings.
