- In highly water-abundant aquifers (unit yield q > 1.0 l/s·m), large water inflow during drilling can hinder progress if rigs lack sufficient drainage. Reverse circulation rotary table drills excel here due to strong debris and water discharge.
- For moderately or poorly water-abundant aquifers, choose high-torque rigs like hydraulic power head drills to break rocks effectively, as drilling speeds are slower.
- Adjust mud properties based on water abundance: enhance wall protection for high-abundance areas and ensure debris-carrying efficiency for low-abundance ones, boosting rig performance across different aquifers.water well drilling rig
