Pebble Layer Drilling Methodology

Conventional Drilling Methods

Traditional techniques like diamond drilling, clean water flushing, pipe reaming, and mud circulation are commonly employed, along with rotary drilling, dry drilling, and percussion methods for core extraction. These approaches often encounter challenges in pebble layers, including heavy drilling loads, frequent accidents, low efficiency, and poor core quality.

Advanced Diamond Drilling Tool Method

Our specialized single acting double barrel diamond drilling tools combined with vegetable gum washing fluid represent the most advanced solution for hard, fragile formations. This process utilizes vegetable gum as washing fluid and diamond as the drilling tool, offering:
