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