Core Technology: Torque Output and Rotary Head Design

Torque output is the critical performance metric for deep rock penetration.
- Our rotary head design delivers a maximum torque output of up to $18000 \text{nm}$. This ensures continuous drilling through hard rock layers.
- The rotary head offers a wide speed range, typically $0-120 \text{rpm}$. This accommodates various geological formations.
- High torque capacity is essential for successfully completing ultra-deep drilling tasks.
Maximizing Penetration: Selecting the Right Down-the-Hole Hammer

Choosing the appropriate down-the-hole hammer is paramount in rock drilling.
- We recommend matching a hammer capable of handling $30 \text{Bar}$ pressure for a $\emptyset 250 \text{mm}$ borehole.
- In hard granite geology, our machines can achieve an average drilling speed of $\approx 15 \text{m}/\text{hour}$.
- Correctly matching the compressor capacity is vital for the efficient operation of the DTH hammer.
Deep Hole Stability: The Casing Drive System

Maintaining borehole integrity is a major challenge in fractured or loose rock.
- Our specialized casing drive system supports a maximum casing diameter of $\emptyset 600 \text{mm}$.
- The rig is capable of driving casing to depths of $\geq 100 \text{m}$.
- The casing drive is a necessary safeguard for deep well drilling rig missions in complex ground conditions.
Borehole Cleaning Power: Mud Pump System and Compressor Capacity
Efficient hole cleaning is essential for maintaining optimal drilling speed.
- Our powerful mud pump system provides a flow rate of $1500 \text{l}/\text{min}$. The pressure can reach $35 \text{bar}$.
- The compressor capacity must be matched to the bore diameter. For example, we recommend a $40 \text{m}^3/\text{min}$ compressor at $25 \text{bar}$ pressure.
- Strong mud circulation is critical for achieving ultra-deep drilling depth.
Operational Efficiency: Rod Handling Automation and Reduced Pipe Change Time
Rod handling automation is key to boosting efficiency.
- Our automated system can reduce the drill pipe change time by $\geq 50\%$.
- This significantly increases the overall drilling speed for ultra-deep drilling depth projects.
- Operators can focus on drilling parameters instead of repetitive physical labor.
Safety and Compliance: Engine Standards and Remote Monitoring
Safety and environmental compliance are fundamental global market requirements.
- Our diesel engines comply with global Tier 4 / Stage V emission standards.
- The rig is equipped with an emergency stop system, with a reaction time of $\leq 3 \text{seconds}$.
- Remote monitoring capabilities provide real-time data feedback, ensuring safe operation of the deep well drilling machine.
Application Expansion: Geothermal and Exploration Uses
The application of the deep rock well drilling rig extends beyond simple water wells.
- For geothermal energy projects, bore diameters are typically around $\emptyset 200 \text{mm}$.
- Our rigs maintain downhole temperature stability within $\pm 2^\circ \text{C}$. This is vital for heat exchange systems.
- Our equipment is the top choice for geological exploration and advanced deep well drilling rig projects.
