The 1000HP skid-mounted land drilling rig is designed to meet the demanding requirements of onshore drilling operations. With a powerful 1000HP DC electric drive, this rig offers stepless speed regulation for drawworks, rotary tables, and mud pumps, ensuring smooth and precise control during drilling activities. The rig’s advanced AC-SCR-DC transmission technology allows for seamless performance under high-pressure and high-displacement conditions, making it suitable for various drilling depths, including 3200m with 5″ drill pipe and 4000m with 4 1/2″ drill pipe.
Key features include a robust hydraulic disc brake system on the drawworks, ensuring reliable braking and enhanced safety. The ZJ40D also comes with a comprehensive driller’s cabin, offering a centralized control system with PLC logic control, real-time monitoring, and data storage capabilities. This setup reduces manual labor, improves operational safety, and enhances drilling efficiency.
The rig’s mast and substructure are designed for ease of transport and quick setup, with options for swing lift or double-lift systems. The rig can be equipped with top drive drilling equipment to further enhance its operational capabilities. The ZJ40D’s flexibility, combined with its power and precision, makes it an ideal choice for high-performance drilling in challenging environments.
SMKST provides a range of internationally compliant components and accessories for the ZJ40D, ensuring compatibility and optimal performance across all drilling operations.
