Ensuring Borehole Stability in Challenging Geological Conditions

Rotary drilling in challenging geological environments, such as loose soil or fractured rock, often poses risks to borehole stability. Advanced rigs like the XCMG Used Rotary Drilling Rig and SANY Used Rotary Drilling Rig provide operators with the tools needed to reinforce boreholes and ensure safety.

Key Challenges to Borehole Stability

1. Loose or Unconsolidated Soil: Causes boreholes to collapse under pressure.
2. Fractured Rock Layers: Introduce instability due to unpredictable rock movements.
3. High Water Pressure: Groundwater intrusion weakens the borehole structure.
4. Improper Drilling Parameters: Excessive speed or torque can destabilize the borehole.
