Patent
·
OSTI ID:6937001
A well packer includes (1) a tubular body arranged at one end for connection with a running string, (2) a unitary gripping member positioned on the body and movable between a casing engaging position and a retracted position, and (3) an articulated head member located on the tubular body having an upper end engagable with the lower end of the gripping member and also being engagable with the casing. The lower end of the articulated head member is engagable with a movable abutment positioned on the tubular body. The well packer also includes packing means located on the tubular body that is arranged to be deformed into sealing engagement with the casing. The articulated head member engages the unitary gripping member and the casing to transfer a portion of the eccentric load of the gripping member into the casing and thus prevent the imposition of a moment on the tubular body.
