Industrial-grade Full Mechanical Drive Reliability
Adopts mature diesel-driven full mechanical transmission system with centralized power output, featuring strong anti-interference capability, stable high torque output and excellent overload resistance under continuous heavy-load conditions. It works independently without external grid power supply, perfectly adapting to remote wilderness, off-grid oilfields and harsh field construction environments. With minimal hydraulic and electronic vulnerable parts, the equipment maintains ultra-low failure rate and long-cycle continuous operation stability for medium-deep well drilling.
L-J Lightweight & Compact Structural Upgrade
On the premise of maintaining complete 4000m medium-deep well heavy-load drilling capacity, the whole machine is optimized for lightweight structure and streamlined layout. The derrick, substructure and power skid realize scientific weight reduction and size compression, greatly reducing overall transportation volume and dead weight. It effectively lowers road transportation restrictions and foundation bearing requirements, solving the migration difficulties of traditional heavy ZJ40 rigs in complex terrain projects.
Modular Skid Rapid Deployment System
All core functional units adopt standardized integrated skid modular design with precise positioning and quick-locking connection structures. The rig requires no complicated on-site calibration or professional foundation treatment, realizing fast field assembly, splicing and commissioning. It significantly shortens rig-up and project startup cycle, and supports frequent cross-well and cross-region turnover for batch well group development.
Reinforced Medium-deep Heavy-load Drilling Performance
Equipped with upgraded high-rigidity K-type open-front derrick and optimized heavy-duty hoisting system. The power matching and lifting torque are comprehensively enhanced to adapt to medium-hard rock, dense formation and complex composite geological conditions. It effectively suppresses drilling vibration and wellbore deviation, ensuring stable, high-efficiency and high-quality well forming during long-term 4000m deep well cyclic operation.
Low Operation & Maintenance Comprehensive Cost
Adopts intuitive mechanical shift control and centralized operation logic with low operator technical threshold. All wearing parts adopt international universal standard specifications with mature global supply channels. The robust and simplified mechanical structure greatly reduces daily maintenance difficulty, field downtime loss and long-term spare parts reserve investment.
Full-condition Harsh Environment Adaptability
Key load-bearing steel structures undergo multi-layer weather-resistant, wear-resistant and anti-corrosion treatment. Core transmission and moving components are equipped with dust-proof, sand-proof, drought-resistant and wide-temperature adaptive protection. The whole machine can operate stably in plains, hills, Gobi deserts and mountainous areas, adapting to high-temperature dry, windy dusty and low-temperature cold field working conditions.
