Managing Fractured Rock Conditions During Rotary Drilling

Fractured rock formations present significant challenges for rotary drilling, including borehole instability and excessive tool wear. Advanced equipment like the XCMG Used Rotary Drilling Rig and SANY Used Rotary Drilling Rig provide the capabilities needed to manage these conditions effectively.

Key Challenges of Fractured Rock Formations

1. Borehole Collapse: Irregular and fragmented rock layers destabilize boreholes.
2. Increased Vibrations: Drilling through uneven surfaces generates vibrations that risk equipment damage.
3. Tool Wear: Fractured rocks are abrasive, accelerating the degradation of drill bits.
4. Unpredictable Water Ingress: Rock fractures often create pathways for groundwater intrusion.
