Aiming at clay particle adhesion to drill tools, four technologies have been developed:Plataforma de perforación de pozos de agua

 

  1. Nano-coating:
    Spray titanium dioxide superhydrophobic coating on drill pipes, reducing adhesion by 70%.
  2. Vibration drag reduction:
    Install high-frequency vibrators (50Hz frequency) on bits, achieving 90% clay shedding rate.
  3. Airflow assistance:
    Use gas-liquid mixed slag discharge to disrupt clay adsorption structure with compressed air.
  4. Surface modification:
    Apply diamond coating to bit alloy teeth, decreasing surface energy by 65%.water well drilling rig
