Abstract
A downhole mechanical anchor setting system which can be positively set in variable positions. More specifically, a mechanical anchor setting system for anchoring a downhole assembly in a well bore. The system includes a mandrel which is longitudinally moveable within a sleeve and a slip system operatively connected to the sleeve and the mandrel for gripping the casing or formation of the well bore when in an engaged position. The system also includes a setting control system operatively connected to the sleeve and the mandrel for selectively setting the slip system in any one of the engaged position, a disengaged position allowing downhole movement of the system and an intermediate position allowing uphole movement of the system without engaging the slip system.
Claims9
A mechanical anchor setting system for anchoring a downhole assembly within a casing or formation of a well bore, the system comprising:
- a mandrel longitudinally moveable within a sleeve;
- a slip system operatively connected to the sleeve and the mandrel for gripping the casing or formation when in an engaged position;
- and
- a setting control system operatively connected to the sleeve and the mandrel for selectively setting the slip system in any one of the engaged position, a disengaged position allowing downhole movement of the system and an intermediate position allowing uphole movement of the system without engaging the slip system.
A mechanical anchor setting system for anchoring a downhole assembly against a downhole casing or formation in a well bore, the setting system comprising a mandrel longitudinally moveable within a sleeve, the mandrel including a slot system in operative communication with a pin on the sleeve for selective actuation of a slip system operatively connected to the sleeve and the mandrel for gripping the casing or formation, the slot system and pin operable between an engaged, a disengaged and an intermediate positions by successively moving the mandrel uphole and downhole, the engaged position for engaging the slip system, the disengaged position for moving the setting system downhole and an intermediate position for moving the setting system uphole without engaging the slip system.
