In the oil drilling industry, the 2JW Swivel is a type of rotary joint used to connect the drill pipe and the drill bit. Its primary function is to allow the drill string to rotate during the drilling process without impeding the progress of the drill bit. Here is an explanation of the uses and functions of the 2JW Swivel:

Transmit Torque and Rotational Force:The 2JW Swivel allows the drill pipe to transmit torque and rotational force to the drill bit, enabling the bit to rotate and penetrate the formations in the wellbore. This is crucial for drilling through formations and exploring underground oil and gas resources.

Reduce Drill Pipe Twisting:During drilling, resistance from underground rock formations can cause the drill pipe to twist. The rotational function of the 2JW Swivel helps to reduce twisting of the drill string, prolonging its lifespan and reducing maintenance costs.

Maintain Drilling Fluid Circulation:The 2JW 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 ensures 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 2JW Swivel connects to the drill bit below, serving as a critical link between the drill pipe and the drill bit, ensuring smooth connection and transmission of power between the two.

In summary, the 2JW Swivel is an indispensable piece of equipment in drilling operations, allowing the drill string to rotate while maintaining the progress of the drill bit and ensuring continuous circulation of drilling fluid. This contributes significantly to the efficiency and safety of oil drilling operations.
