摘要
A cable cutting sub or coupling for drilling, production, well logging or troubleshooting operations in wells, comprising a drilling pipe in which a cable is engaged. This sub allowing the cable to be severed if required comprises a tubular body in which a liner may slide. The side wall of said tubular liner has an opening in which is engaged a member for severing the cable and said liner is movable from a first position offering free axial passage to the cable to a second position in which an internal shoulder of said liner urges the cable against said severing member.
