Industry pain points
Traditional directional drilling requires frequent tripping to adjust the stabilizer size, resulting in:
⛔ Homework stagnation: A single drilling trip takes 6-12 hours
⛔ Trajectory deviation: Sliding drilling accounts for more than 40%, and the wellbore curvature is discontinuous
⛔ Cost surge: Non production time (NPT) accounts for 25% of total drilling costs
Core technology breakthrough
Underground dynamic variable diameter system
By using hydraulic/electrical control modules, the stabilizer outer diameter (range: Φ 216mm → Φ 241mm) can be adjusted in real-time while drilling, achieving:
Switching between increasing/decreasing tilt mode: response time<5 minutes
Rotational guidance collaborative control: closed-loop adjustment of wellbore inclination angle (accuracy ± 0.1 °/30m)
Full rotation drilling: 100% cancellation of sliding drilling

Five core values
✅ Precise trajectory control
The deviation angle error of the well is less than 0.5 °, and the hit rate of the horizontal target center is 98%
✅ The efficiency of homework has increased significantly
Reduce 90% of drilling trips and save 5-7 days of construction time for a single well
→ Mechanical drilling speed increased by 20-30% (rotary drilling accounts for 100%)
✅ Optimization of wellbore quality
→ Continuous smooth trajectory (Dogleg Severity<3 °/30m)
The efficiency of rock debris bed removal has been increased by 45%
✅ Full lifecycle cost compression
Save 15% on fuel/mud consumption
Reduce drilling tool fatigue damage by 60%
✅ Intelligent integration compatibility
→ Support Landmark/Drillworks drilling software
→ Adapt to Rotating Guidance System (RSS)
Application scenarios
Large displacement horizontal well: continuous control of horizontal sections exceeding 3000m
Multi branch well: precise diversion of main and lateral branches
Complex formations: real-time anti sticking drilling in shale/salt gypsum layers
Deepwater drilling: reducing the risk of drilling in deepwater areas
