Salt layers are mainly made of soluble minerals like rock salt and gypsum,
with high solubility and low strength.
Due to their special physico-chemical properties,
salt layers creep and plastically deform under pressure and temperature changes.
This brings many challenges to water well drilling rig operations:
- During drilling, salt layers easily shrink in diameter, reducing borehole size and jamming drill tools.
- Brine formed by salt layer dissolution is highly corrosive, damaging rig equipment.
To tackle these issues:
3. Survey the salt layer’s thickness, burial depth, and composition in detail before operation.
4. Choose suitable drilling techniques and corrosion-resistant rig equipment based on actual conditions to lay the foundation for follow-up work.water well drilling rig
