Motorhead Assembly
Application
The motorhead assembly combines the main tool components used in coiled tubing operations in modular form. The combined tool length has been greatly reduced to allow ease of handling and deployment in the well and also to effectively reduce the bending stresses in the bottomhole assembly. The motorhead assembly consists of the coiled tubing connector, dual back pressure valve, hydraulic disconnect, dual circulation sub, and optional lockable swivel.
Advantages
•High tensile strength
•Full torque-through capabilities
•Shorter overall length
•Full internal pressure integrity
•Standardized connections for ease of use
Coiled Tubing Connector
Application
Coiled tubing connectors provide a means of attaching a tool string to the end of the coiled tubing. The connectors, when installed correctly, provide a reliable, strong sealed connection to the coiled tubing. All of the connectors have been designed with either a fishing neck or a slick profile on the OD of the top sub. This will accommodate standard external fishing overshots should the need arise. Coiled tubing connectors have been designed for most sizes of coiled tubing. The coiled tubing connectors are of the slip type or collet type design. The slip type connectors are also equipped with set screws to rotationally lock them from spinning when used in conjunction with tools that create torque such as coiled tubing workover motors.
The connectors use o-ring seals to seal off the coiled tubing in order to maintain pressure integrity for the tool string.
Advantages
•High tensile strength
•High torsional strength for motor applications
•Large ID for maximum flow rates and pump through of actuation balls
•Manufactured with fishing profile on top of connector high pressure/high temperature tools rated to 10,000 psi (689 bar) and 400°F (204°C)
