A water well drilling rig uses different methods across landforms,
as geology and groundwater vary greatly.
-
Mountainous areas: Use crawler rigs with diamond bits for hard rocks. Focus on faults and fractures. A mountain rig found water-rich fractures along ridges, solving local water needs.
-
Plains: Vehicle-mounted rigs with spiral bits work fast in loose sediments. Explore layered pore aquifers. An alluvial plain rig drilled 2 holes/day, mapping 3 aquifer layers via cores.
-
Plateau and coastal areas: Plateau rigs need cold resistance (e.g., low-temp hydraulic oil). They handle permafrost to find water below 50m. Coastal rigs use anti-corrosion drill pipes. One found salt-fresh water at 15m depth, guiding development.

Adapting the water well drilling rig to landforms ensures quality and efficiency. It fits diverse environments for water well drilling rigs.
