Structure features and applications of the bit
1. Optimally designed bit profile suitable for drilling medium formation.
2. Cutting structure is force balanced and bit blade is asymmetrically designed so that the load on bit is balanced which resulting better stability of the bit.
3. Multiple types of high performance PDC cutters are strategically arranged on bit for improved service life of the bit.
4. Shock absorbers are designed to make the bit capable of drilling through formations with hard stringers.
5. Hydraulic system of the bit is optimized using dynamic flow pattern simulation technology to enhance cleaning and cooling effects of the bit to effectively prevent bit from balling.
| Advantage: | Higher nozzle counts and/or fixed ports to best serve cleaning, cooling and cuttings evacuation requirements with available hydraulic flows. Allows for higher flow rates with minimal increase in pump pressure. |
| Benefit: | Optimized ROP and bit life; Longer drilling intervals without need for tripping |
| Feature: | Diamond are impregnated in the matrix behind the PDC cutters |
