Difficulties and Countermeasures in Drilling Wells in Heterogeneous Aquifers-water well drilling rig

Hey guys, heterogeneous aquifers are tricky!water well drilling rig. Their properties vary greatly in space, with different lithology and permeability at each location. Drilling here often causes issues like hole deviation or stuck drills. To tackle these:

  1. Start with geological surveys to understand aquifer characteristics thoroughly.
  2. Use measurement-while-drilling technology to monitor the hole trajectory in real time, adjusting promptly for deviations.
  3. Compound drills combining impact and rotary functions better handle complex strata.
  4. Flexibly change drill bits and adjust parameters based on lithology to ensure successful well-drilling in heterogeneous aquifers.water well drilling rig
