Core advantages

Designed around the operating requirement.

Excellent Mobile Performance & Fast On-Site Deployment

Adopts integrated modular mobile design with truck-mounted or trailer-mounted optional configuration. The whole rig features reasonable weight distribution and convenient integral transportation, effectively solving the problems of cumbersome disassembly, long relocation cycle and high transportation cost of traditional fixed rigs. It realizes rapid rig-up and commissioning after arriving at the well site, greatly shortening auxiliary construction time and improving overall drilling efficiency for scattered well areas.

4000m Medium-Deep Well High-Efficiency Drilling Capacity

Matched with professional ZJ40-grade power and hoisting system, with rated drilling depth up to 4000 meters and static hook load reaching 2250kN. The high-power drawworks and high-efficiency mud pump combination ensures stable rotary drilling power and sufficient wellbore circulation displacement, fully meeting the drilling demands of various medium-deep oil, gas and geothermal wells. It maintains efficient rock-breaking and stable tripping operation under complex formation conditions.

Reinforced Structural Design & High Operation Stability

The derrick and base adopt high-strength alloy steel integral welding and reinforcement process, with excellent structural rigidity, wind resistance and impact resistance. Key load-bearing and transmission components undergo strict NDT flaw detection to eliminate internal defects. The optimized balanced hoisting and vibration reduction structure effectively reduces operation jitter, ensuring long-term stable cyclic drilling and tripping operation in complex well site environments.

Diversified Power & Efficient Transmission System

Supports mechanical, electromechanical and variable-frequency electric drive modes for optional selection. The high-precision transmission box and heavy-duty clutch assembly realize smooth power switching and low-loss torque output. The matched multi-stage speed regulation function adapts to different formation hardness and drilling process requirements, realizing energy-saving and high-efficiency operation while ensuring drilling quality.

Full-Climate Harsh Environment Adaptability

All core power, hydraulic and electrical components adopt wide-temperature anti-aging and sealed protection configuration. The whole machine is coated with enhanced sand-proof, anti-corrosion and weather-resistant protective layer, supporting stable continuous operation within -40℃ ~ +55℃. It perfectly adapts to extreme working environments such as desert high temperature, Gobi wind-sand erosion, muddy well sites and high-altitude cold plateaus.

Intelligent Control & Low Maintenance Cost

Equipped with integrated centralized control cabin and visual operation system, realizing real-time monitoring of drilling parameters, hoisting load, system pressure and operating status. The modular structural layout improves the universality of wearing parts, simplifies daily inspection, lubrication and component replacement procedures, effectively reducing long-term operation and maintenance costs and equipment failure rate.
