In gravel layers with complex and variable geology, sudden changes like
quicksand and cobble layers may increase construction difficulties and risks.water well drilling rig
To address sudden geological changes, conduct detailed site surveys and formulate emergency plans before construction. When encountering quicksand layers, immediately increase mud viscosity and specific gravity to pass through quickly. If unable to pass, backfill the quicksand section with clay or cement soil, then resume drilling after soil stabilization.
- For cobble layers, replace with impact bits to crush cobbles through impact force.
- Strengthen hole wall support simultaneously to prevent cobble collapse.
- Ensure construction safety and progress by adjusting drilling parameters and reinforcing mud wall protection in real time.water well drilling rig
