Drill pipe wear is severe during water well drilling rig in fault zones.
Fault zone rocks are fragmented and uneven in hardness,
making drill pipes bear torque,
pressure,
frequent impacts,
and vibrations.
This causes loosening and wear at pipe joints,
as well as bending and cracking in the pipe body.
Additionally,
groundwater and corrosive substances in fault zones accelerate drill pipe corrosion.
After a construction project in a fault zone,
inspections found multiple drill pipes with varying degrees of corrosion and deformation.
To reduce drill pipe wear:
- Choose reliable, high-strength drill pipes and regularly inspect them for flaws.
- Replace damaged drill pipes promptly to prevent further issues.
- Apply anti-corrosion coatings to drill pipe surfaces to extend service life.water well drilling rig
