Strategies for improving the drilling efficiency of water well drilling RIGS in coal seams

Nuus 127 Sieninge
To improve the drilling efficiency of water well drilling rig in coal seams, measures can be taken from multiple aspects.

 

  1. Optimize drilling parameters: adjust WOB, rotation speed, and propulsion speed based on coal seam hardness and integrity to increase drilling speed while ensuring borehole quality.
  2. Improve bit design: adopt composite blade bits or PDC bits suitable for coal seam drilling to enhance rock-breaking capability.
  3. Introduce efficient slag discharge systems, such as reverse circulation slag discharge technology, to quickly remove cuttings and reduce repeated crushing.
  4. Strengthen equipment maintenance to ensure good performance of all rig components.
  5. Arrange construction procedures reasonably to minimize auxiliary operation time, thereby enhancing coal seam drilling efficiency through comprehensive measures.water well drilling rig
