Hey folks, a confined aquifer isfully saturatedbetween 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.
