The fundamental challenges of water well drilling RIGS in fracture and fault zones

News 182 Views
In fractured and fault zones, water well drilling faces fundamental challenges. Geological movements break stratigraphic structures, forming complex fracture networks and fault interfaces. When drilling, the bit crosses alternating hard-soft rock layers, easily causing deviation in borehole trajectory. Moreover, broken rocks may fall, blocking drill pipe channels, disrupting flushing fluid circulation, and increasing stuck drill risks. For example, a construction site in a fault zone once spent much time resolving a stuck drill due to rock falls, severely delaying the project.water well drilling rig

To address these challenges:

 

  1. Conduct detailed geological surveys in advance.
  2. Optimize drilling operation procedures based on actual conditions.
  3. Implement proactive measures to ensure smooth operations.water well drilling rig
