Product Description

Product Description

AC VF Drive Drilling Rig

Engineered for precision, power, and reliability, our AC variable frequency drive (DB) top drive systems redefine drilling efficiency across all terrains—from shallow wells to ultra-deep explorations.

The drilling rig is equipped with independent driller control room. The gas, electric and hydraulic control, drilling parameters and instrument displays can be arranged unitedly so that it can achieve logic control, monitoring and protection through PLC during the whole drilling. In the mean time, it can also achieve saving, printing and remote transmission of the data. Driller can accomplish all operations in the room which can improve the working environment and decrease the labour intensity of drillers.

Technical Advantages:

Product Features:

1.Superior Depth & Load Capacity – Tackle drilling depths from 2,500m to 9,000m with hook loads up to 6,750 kN.
2.Supports drilling depths from 2,500–9,000 meters (with 114mm drill pipe).
3.Smart AC Variable Frequency Control – Smooth stepless speed regulation for drawworks and rotary table, ensuring optimal torque and RPM in all conditions.
4.0-220 RPM Infinite Speed Control – Broadest speed range available
5.Equipped with high-performance drawworks (735–2,210 KW) and multiple shifts for smooth operation.
6.105 MPa IBOP Pressure Rating – Industry-leading well control

1.Heavy-Duty Components – High-strength sheaves (44"–60"), large swivel bore (75–102mm), and reinforced mast structures (43–48m) for unmatched durability.
2.Energy-Efficient Power – High-capacity drawworks (735–2,210 kW / 1,000–3,000 hp) and mud pumps (960–1,620 kW) minimize downtime.
3.Features optimized sheave diameters (44"–60") and swivel stem through-holes (75–102mm) for seamless integration.
4.Reinforced mast structures (43–48m working height) and elevated drill floors (7.5–12m) ensure stability and safety.
5.Safety & Adaptability – Elevated drill floors (7.5–12m) and clear heights (6.26–10m) ensure safe, flexible operations.
