Overcoming Borehole Collapse in Inclined Rock Layers with Rotary Rigs

Inclined rock formations pose significant risks to borehole stability, requiring advanced solutions to prevent collapse and maintain precision. The XCMG Used Rotary Drilling Rig and SANY Used Rotary Drilling Rig are equipped with innovative features designed to tackle these challenges effectively.

Common Causes of Borehole Collapse in Inclined Rock

1. Uneven Rock Layers
   Varying angles and structures in rock layers create instability during drilling.
2. Excessive Stress on Borehole Walls
   Inclined formations exert uneven pressure on borehole walls, increasing collapse risk.
3. Inadequate Stabilization Measures
   Failing to apply temporary casings or drilling fluid results in insufficient support.
4. Tool Misalignment
   Misaligned tools can compromise borehole stability, especially in angled formations.
