Hey guys, different aquifers need different drilling techniques!水井鑽機

 

  1. In loose pore aquifers, reverse circulation drilling works well, quickly removing cuttings to speed up drilling.
  2. For fractured aquifers, impact-rotary drilling is better—breaking rocks with impacts while reducing disturbance to fractures.
  3. In karst aquifers, down-the-hole hammer drilling excels at crushing hard rocks and handling complex solution cavities.
  4. Confined aquifers require balanced pressure drilling to control mud pressure and prevent water inrush.
  5. Phreatic aquifers can use direct circulation drilling to meet needs. Picking the right technique for aquifer traits maximizes water well rig efficiency and ensures successful well-drilling.
