The rotary joint (also commonly known as the rotary assembly/swivel joint) is a core component of the hoisting system and drilling operations on an oil drilling rig. As a crucial bridge connecting the hoisting system and the drill string, it not only drives the drill string to rotate 360° to complete drilling operations but also serves as the core channel for high-pressure drilling fluid circulation. Combining high-strength mechanical structure with precise fluid handling capabilities, it is an indispensable core piece of equipment for ensuring safe, efficient, and continuous drilling operations on both onshore and offshore drilling platforms.
Core Functions
- Power Transmission and Drilling Drive: It efficiently transmits the rotational motion of the winch/hoisting system to the drill string, driving it to rotate 360° 360°. This, in conjunction with the drill bit, enables core operations such as rock breaking, drilling, and tripping. It is the heart of drilling power transmission.
- Reliable Drilling Fluid Circulation Channel: It creates a leak-free, high-pressure fluid channel, allowing the drilling fluid (mud) to circulate continuously and stably throughout the operation. This facilitates bottom hole cleaning, cuttings removal, and drill bit cooling, ensuring continuous drilling operations and preventing accidents such as stuck drill bits and burnt drill bits.
- High-Strength Load Bearing: Constructed from high-quality alloy steel using a precision-machined integrated high-strength structure, it can withstand extremely high axial loads, radial pressures, and severe torques during drilling operations. Perfectly suited for the harsh conditions of deep wells, ultra-deep wells, and complex geological formations, its robust structure offers excellent impact resistance.
- Stable Sealing and Fluid Control: Equipped with high-specification bearings, high-performance seals, and robust connection interfaces, it ensures sealing and stability during rotation from the structural source, preventing drilling fluid leakage and ensuring smooth operation of rotating components, eliminating operational failures, and maintaining operational continuity.
- Versatile Adaptability: Widely compatible with onshore and offshore drilling platforms (including marine environments), it is compatible with different drilling depths, various drilling rig models, and multiple drill pipe configurations. It is a core component that provides one-stop solutions for drilling needs in multiple fields such as oil and gas exploration and geological exploration.
- International Standards Compliance:Strict adherence to API and international drilling equipment industry standards in design, production, and performance testing ensures high reliability, operational safety, and long-term durability from the design stage, meeting the highest global drilling industry standards.
