ABSTRACT:
An adapter kit is shown for attaching a setting tool of the type having a power actuated outer sleeve and a cooperating inner tubular member to a well packer. The adapter kit includes a tubular mandrel having an upper end which is adapted to be connected to the setting tool inner tubular member and has a ramp area formed in a portion of the mandrel exterior. A collet having a collet body and a plurality of expansive collet fingers is slidably received about the tubular mandrel with the ramp area beneath the collet fingers to expand the fingers outwardly with respect to the mandrel. The collet fingers are provided with an outer threaded surface which is adapted to engage a mating internally threaded surface of the well packer when the collet fingers are expanded to the proper thread diameter by passing the mandrel ramp beneath the collet fingers. The collet is releasably secured in position by a shear wire with the fingers in the outwardly expanded position for engaging the packer internally threaded surface. A setting sleeve is engagable with the setting tool power actuated outer sleeve and engages the packer whereby actuation of the setting tool serves to move the setting tool and tubular mandrel in opposite relative directions to sever the shear wire and move the ramp area from beneath the collet fingers to disengage the collet and setting tool from the packer. The setting tool and setting sleeve can then be retrieved by a wireline from the wellbore leaving the packer in position.
