Fissure aquifers and water well drilling rig challenges

Haberler 40 Views
Hey folks, fractured aquifers consist of hard rocks. water well drilling rig.Weathered fractured aquifers often occur where rock outcrops or bedrock is shallow. In China’s coal mines, weathered fracture zones are typically 30-60m deep, with fewer fractures below. Deep interlayer fractured aquifers’ water abundance depends on lithology and tectonic fractures. Drilling here poses challenges:

 

  1. Rock fragmentation may cause drill pipe jams.
  2. Fractures can lead to mud loss.
  3. Impact drills, like wireline percussion rigs, work well by crushing rocks via vertical motion, adapting to complex fractured strata. Clear cuttings promptly to avoid blockages.water well drilling rig
