Correction and prevention of Positioning Deviation of Water Well Drilling RIGS in Soft soil layers

ニュース 17 Views
The instability of soft soil layers often causes positioning deviations in water well drilling rig during construction, affecting the verticality and positional accuracy of water wells.

 

To prevent positioning deviations, here are key measures:

  1. Prepare the Site Thoroughly Before Drilling:
    • Level the site and mark measurement lines to ensure a stable rig foundation.
    • Use high-precision instruments like total stations and GPS to monitor the rig’s position and verticality in real time.
  2. Conduct Regular Re-Measurements During Drilling:
    • Recheck the position and verticality at regular depth intervals.
    • Adjust promptly once deviations are detected to avoid cumulative errors.
  3. Use Correction Tools and Enhance Training:
    • Employ deviation-correcting tools (例えば。, eccentric bits, bent sub connectors) for significant deviations.
    • Train construction personnel to improve their awareness of positioning accuracy control.water well drilling rig
