Advanced Techniques for Sand Layer Stability in Drilling

Drilling in sand layers requires advanced techniques to address challenges such as borehole collapse and fluid infiltration. The XCMG Used Rotary Drilling Rig and SANY Used Rotary Drilling Rig offer cutting-edge solutions to ensure safe and efficient operations in these challenging conditions.

Key Challenges in Sand Layer Drilling

  1. Borehole Collapse Risk
    Sand’s loose and non-cohesive nature increases the risk of collapse during drilling.

  2. Effective Debris Management
    Fine sand particles can clog boreholes, reducing efficiency and causing delays.

  3. Tool Wear and Durability
    The abrasive properties of sand accelerate wear on drill bits and other components.

  4. Fluid Stabilization
    Maintaining proper fluid circulation is critical to stabilizing sand layers and ensuring smooth drilling.

Features of XCMG and SANY Rotary Drilling Rigs

  1. High-Torque Systems
    The XCMG Used Rotary Drilling Rig delivers consistent torque, adapting to the instability of sand layers.
