Hey folks, a confined aquifer is
fully saturated between two impermeable or low-permeable layers. Drilling in confined aquifers requires high-standard water well drilling rig.
- High water pressure here needs rigs with sufficient strength and sealing.
- Rotary table drills are commonly used, especially those with high-performance mud pumps and quality drill tools.
- During drilling, strictly control mud density and viscosity to stabilize the borehole wall, preventing water inrush or collapse.
- Monitor well pressure in real time and adjust drilling parameters to ensure safe, smooth operations and access to high-quality wat er from the confined aquifer.water well drilling rig.
