Title: CABLE HEAD WITH CABLE SHEAR MECHANISM AND METHODS RELATED THERETO
Abstract:
A cable head with cable shear mechanism, and method for installing the same. The cable head for attaching to a wireline to support oilfield equipment in a wellbore formed from a housing with a cable bore. The housing includes a tapered sleeve with a tapered sleeve cable bore, a sliding bell with a sliding bell cable bore, a drive pinch cylinder, a linear biasing mechanism positioned between the tapered sleeve and the drive pinch cylinder, a plurality of shear pins disposed partially into the housing and though the drive pinch cylinder, wherein each shear pin is adapted to withstand from 100 pounds to 2000 pounds of shear load, a pair of slidable cutting segments and a pair of slidable cutting segment guides. When cable load exceeds a preset limit, the shear pins shear allowing the slidable cutting segments to be moved up the slidable cutting segment guides to impact and shear the cable.
