The abundant and complex groundwater in fault zones profoundly affects
water well drilling rig operations. Fault zones serve as good channels for groundwater migration, so drilling may encounter massive water inflow, increasing drilling difficulty and risking borehole collapse. Meanwhile, the complex chemical composition of groundwater may corrode drilling tools and equipment. For example, a project in a fault zone saw rapid rusting of drill pipes due to highly corrosive groundwater, shortening their service life.
To address these issues:
- Implement dewatering measures to lower the groundwater level.
- Use corrosion-resistant drilling tool materials like stainless steel drill pipes.
- Add corrosion inhibitors to flushing fluids to protect drilling equipment.water well drilling rig
