DQ30B Top Drive System: Redefining Drilling Efficiency and Reliability for 3000-Meter Deep Wells

In high-intensity drilling operations, equipment performance directly determines project profitability. The DQ30B Top Drive System integrates cutting-edge technology with robust quality to deliver an efficient, stable, and safe power solution for 3000-meter deep well exploration.

Core Advantages

• Powerful Performance & Precise Control
  With a rated continuous output torque of 27.5 KN.m and a maximum break-out torque of 41 KN.m, combined with a 0–200 r/min stepless speed regulation spindle, it easily handles complex formations and efficient tripping operations. The main motor’s 290KW rated power ensures consistent and stable power output.
• Exceptional Load Capacity & Safety Assurance
  An 1800 KN rated load and 27.5 KN.m static maximum braking torque, paired with a 105 MPa high-pressure IBOP (hydraulic/manual dual mode), significantly enhance well control safety. The back clamp accommodates 85–187mm drill pipes, offering a wide clamping range and flexible operation.
• Efficient Mud Circulation & Compact Design
  The mud circulation channel’s rated pressure reaches 35/52 MPa in dual modes, meeting high-pressure circulation demands. With only 502.5mm between the spindle center and guide rail center, the compact structure optimizes derrick space. Overall dimensions of 4156mm × 970mm × 1200mm adapt to confined rig environments.
• Extreme Environment Adaptability
  From -45℃ extreme cold to 55℃ high temperatures, the DQ30B maintains stable operation. The hydraulic system operates at 0–14 MPa, and the electric control room supports 600 VAC/50Hz input, compatible with global mainstream oilfield power standards.

Application Scenarios
Ideal for onshore and offshore platform medium-depth wells and directional drilling, particularly suited for 3000-meter drilling depth requirements with 114mm drill pipes. It is the optimal choice for improving drilling efficiency and reducing overall costs.
