Selection and wear control of drill bits for sand and gravel layer water well drilling RIGS

News 73 Views
In gravel layers, hard and angular particles cause severe wear on well-drilling bits. Traditional bits often suffer from chipped cutting teeth and excessive body wear, reducing drilling efficiency and increasing costs.water well drilling rig

For gravel layer characteristics, choose wear-resistant bits like alloy tooth bits and PDC composite bit. Alloy tooth bits with hard alloy inserts offer strong impact resistance and wear resistance. PDC composite bit uses polycrystalline diamond compact for high cutting efficiency in gravel.

 

  1. Optimize bit structure design by adding gauge protection to reduce side wear.
  2. Regularly inspect bit wear during construction and replace severely worn bits promptly.
  3. Adjust drilling parameters reasonably to minimize bit damage.water well drilling rig
