DQ30BQ Top Drive System: Superior Spatial Compatibility and Enhanced Wellbore Operational Flexibility
Engineered specifically for optimized performance in 3,000-meter deep well operations, the DQ30BQ Top Drive System builds upon the proven excellence of the DQ30B series. Through key structural enhancements, it delivers superior derrick spatial compatibility and wellhead operational efficiency, making it the upgrade of choice for modern drilling platforms.
Core Competitive Advantages
- Optimized Spatial Layout, Enhanced Operational Freedom
The working height (with 96″ lifting links) is increased to 5205mm, providing greater vertical space for handling tools below the main shaft. The distance between the main shaft center and guide rail center is extended to 532.5mm, further optimizing the clearance between the equipment and the derrick structure. - Full 360° Rotation, Doubled Operational Efficiency
The rotating link adaptor provides continuous 0-360° rotation, significantly simplifying processes such as pipe handling and tool positioning. This leads to marked improvements in wellsite preparation and tripping efficiency. - Proven Robust Performance, Reliable Power
With a rated continuous output torque of 27.5 kN.m, a maximum break-out torque of 41 kN.m, and a main motor rated power of 290 kW, the system ensures powerful and reliable performance even in complex geological conditions. - Comprehensive Safety Assurance, Unfazed by Extreme Environments
A static maximum braking torque of 27.5 kN.m and a 105 MPa IBOP (Hydraulic/Manual) provide a dual safety guarantee for well control. The back clamp accommodates 85-187mm drill pipes, ensuring broad applicability. The system maintains stable operation across a wide ambient temperature range of -45°C to 55°C.
Technical Highlights
- Mud Circulation System: Dual pressure modes (35/52 MPa) provide ample capability for high-pressure formations.
- Hydraulic & Electrical Systems: Hydraulic system working pressure 0-14 MPa; Electric control room input power 600 VAC/50Hz, ensuring strong compatibility.
- Overall Design: Compact dimensions of 4740mm × 970mm × 1267.5mm meet the strict size requirements of various worksites.
Application Value
The DQ30BQ is particularly suited for land rigs and offshore platforms with space constraints. Its enhanced spatial adaptability and 360° rotation functionality make it ideal for applications with higher demands for flexibility and efficiency, such as directional wells and cluster wells, significantly boosting overall operational efficiency and reducing total operating costs.
