In the oil drilling industry, the “3JW Swivel” is a type of rotary joint used to connect the drill pipe and the drill bit. Here is an explanation of the uses and functions of the 3JW Swivel:
Transmit Torque and Rotational Force:The 3JW Swivel allows the drill pipe to transmit torque and rotational force to the drill bit, enabling the bit to rotate and advance in the wellbore. This is crucial for effectively penetrating formations and achieving successful drilling operations.
Reduce Drill Pipe Twisting: During drilling, resistance from underground rock formations can cause the drill pipe to twist. The rotational function of the 3JW Swivel helps to reduce twisting of the drill string, prolonging its lifespan and reducing maintenance costs.
Maintain Drilling Fluid Circulation:The 3JW Swivel features passages that allow drilling fluid to flow through the rotary joint and back into the drilling fluid circulation system on the surface. This helps ensure continuous cleaning of the wellbore, cooling of the drill bit, and stabilization of the wellbore walls during drilling operations.
Connect Drill Bit and Drill Pipe:Positioned at the top of the drill string, the 3JW Swivel connects to the drill bit below, serving as a critical link between the drill pipe and the drill bit. It ensures smooth connection between the two and allows the drill string to rotate without impeding the progress of the drill bit.
Overall, the 3JW Swivel is an important piece of equipment in oil drilling operations, allowing the drill string to rotate while maintaining the progress of the drill bit and ensuring continuous circulation of drilling fluid, thereby providing crucial support for efficient and safe drilling operations.
