In rotary drilling construction, maintaining borehole verticality is essential for pile quality, construction safety, and project efficiency. Borehole deviation can cause delays, extra costs, and quality problems.
Water well drill pipe experts recommend the following key methods to improve drilling accuracy:
1. Monitor Verticality During Drilling
Check borehole alignment continuously during construction to detect and correct deviations early.
2. Inspect Casing Straightness
Before drilling, inspect and correct the straightness of each casing section on level ground to ensure accurate borehole positioning.
3. Calibrate Connected Casings
After assembly, all casing sections should be checked again to maintain stable and vertical drilling performance.
4. Correct Deviation Promptly
If borehole deviation occurs, use the rotary drilling rig’s casing driver to make timely corrective adjustments.
Careful and professional operation helps improve drilling quality, reduce construction risks, and avoid unnecessary economic losses.
