• Strong Arm High Torque Orientation Tool

    Description

    The 'Strong Arm' Orientation Tool was developed to deliver a higher torque turn than existing indexing tools on the market size for size. The 'Strong Arm' Orientation Tool is designed for coiled tubing applications where rotational control of tools below the Bottom Hole Assembly is a requirement.

     

    The 'Strong Arm' Orientation Tool is also suitable for most other coiled tubing applications where a high torque downhole rotation of the lower string is required e.g 'hookwall' overshot use for fishing below the tailpipe.

     

    Operation

     

    The Orientation Tool is operated by flow activation. By increasing the flow rate a pressure is achieved at the tool, typically in the range of 1000 psi, whereupon a piston will stroke downwards. This downward movement will rotate a Drive Shoe by means of a helical Drive Shaft, converting linear motion into torque. The degree of orientation imparted is dependent upon the distance the piston moves. This ensures that rotation is truly stepless.

     

    The Drive Shoe will normally rotate a maximum 45º in a single cycle. To repeat the cycle, the flow rate is reduced back to normal circulation, the tool will stop rotating and become rigid. The piston will automatically return to its start position so that the tool is reset. The indexing cycle can now be repeated as before.
