Bit Selection and Maintenance of Water Well Drilling Rig in Silty Sand Layer Areas

News 22 Views
  1. Bit Selection for Different Conditions 
  • Choose carbide scraper bits for fine-grained silty sand layers. Their sharp blades cut silty sand quickly, and carbide material resists wear to extend service life.water well drilling rig
  • Use roller cone bits for gravel-containing silty sand. The rolling crushing action of cones effectively handles gravel, improving drilling efficiency.

 

  1. Post-Operation Cleaning and Inspection
    After each drilling operation, promptly clean silty sand attached to the bit surface. Check wear on blades or cones, and replace or repair them immediately if severely worn.water well drilling rig
  2. Routine Lubrication and Dynamic Adjustment

  • Regularly lubricate the bit to ensure flexible rotation and reduce drilling resistance.
  • Adjust bit types according to changes in silty sand layers and drilling depth to adapt to different working conditions, ensuring drilling quality and efficiency.
