Best Bits for Clay & Loam in Water Well Drilling Rig

Новости 52 Views
In water well drilling rig operations, clay and loam—soft soils with unique traits—often bring challenges. Clay is highly plastic and sticky; loam blends stickiness with slight looseness.

 

Their stickiness makes cuttings cling to bits, causing “clogging” and reducing cutting power. After the bit leaves, the soil shrinks back, increasing drilling resistance. These issues slow work and damage equipment.

 

Here’s how to handle them with water well drilling rigs:

 

  1. Use scraper bits paired with spiral drill pipes. Scraper bits have large cutting edges to shear soil fast. Their open design reduces debris buildup, preventing clogging.
  2. Spiral drill pipes work with the bits. Their spiral blades carry cuttings out quickly, stopping secondary bonding in the hole.
  3. Control operations wisely. Keep rotation speed low (30-50 rpm) to balance cutting and reduce friction. Use low-viscosity, high-flow mud—it lubricates, carries cuttings, and forms a tough mud cake to stop shrinkage.

With the right tools and methods, water well drilling rig conquer clay and loam easily, keeping work on track.
