ABSTRACT:
A coiled tubing operated full opening completion tool system for use in a well bore. The tool system comprises a completion tool, such as a casing valve, disposed in a well casing. The tool system further comprises a positioner tool for opening and closing a sliding sleeve in the casing valve. A hydraulically actuated operating cylinder section, including opening and closing cylinder sections, is used to actuate the positioner tool to open and close the casing valve sleeve. Hydraulic slips lock the tool in position in the well bore during actuation. The tool further comprises a jetting tool which is hydraulically actuated between an open position thereof in which fluid in the tool is communicated through a jetting nozzle aligned with a port in the casing tool and a closed position. A J-slot and lug are provided in the positioner tool for controlling the longitudinal position thereof during opening and closing of the casing valve sleeve. Another J-slot and lug are provided in the jetting tool for controlling the longitudinal position of a jetting sleeve therein for opening and closing the jetting tool. A spring in the jetting tool biases the jetting sleeve toward its closed position. The tool is specifically designed for, but not limited to, use on coiled tubing.
