The multi-point uniform stress distribution design eliminates structural deformation, shaking and displacement during ultra-long-cycle heavy-load operation, providing ultimate structural stability for high-intensity ultra-deep well construction.

Super-High Heavy-Duty Mast & Large-Caliber Rotary Table

Equipped with 48m high-strength integral lattice mast and 1257.3mm (49.5”) large-diameter rotary table, matching φ42mm ultra-high-strength steel wire rope. It supports super-large-size casing running, high-torque rotary drilling and complex stratigraphic exploitation, perfectly meeting the rigorous construction requirements of ultra-deep large-diameter borehole projects.

Full Extreme Environment Adaptive Stability

Equipped with industrial-grade oversized circulating heat dissipation system, upgraded reinforced wear-resistant transmission structure and full-coverage military-grade anti-corrosion, dust-proof and ultra-low-temperature resistant coating. It stably supports 24-hour uninterrupted full-load operation in extreme scenarios including -45℃ ultra-low-temperature high altitude, 55℃ high-temperature deserts and drought Gobi areas, with superior environmental adaptability and extended service life.

High-End VFD Intelligent Full Safety Control System

Matched with luxury fully enclosed intelligent control cabin, integrated high-precision VFD variable frequency drive system and MCC centralized control system. Equipped with full-process real-time parameter acquisition, dynamic load intelligent feedback and multi-level redundant safety interlock protection devices, it realizes visualized, precise and automatic ultra-deep well construction, minimizing manual errors and upgrading overall construction intelligence and safety standards.
