Drilling Rig Components & Operation
The primary drilling method utilizes rotary table with mud positive circulation. When equipped with appropriate tools, it can adapt to various drilling applications.
The rig operates effectively in clay, sand layers, and bedrock formations. The pressure mechanism enables pressurized drilling for improved shallow hole efficiency, transitioning to decompression drilling as depth increases.
Winch System
- Main Winch: For lifting drilling tools and lowering well tubes
- Auxiliary Winch: Drives impact samplers, coring tools, and sand lifting cylinders; also used for well washing
- Tool Winch: Handles single vertical root movement and tool lifting to reduce manual labor
Performance Features
- Optimal weight distribution between axles for superior driving and off-road capability
- Ample maintenance space for all core components
- Excellent resistance to wind, sand, and seismic activity
- Operates in temperatures from -20°C to 45°C
- Premium power components and hydraulic systems from reliable manufacturers
- Standardized bearings and oil seals for easy replacement
