Core recovery increased by 35%, bit life extended by over 40%, and crown temperature dropped significantly—demonstrating strong performance in complex formations.

A bottom-jet hydraulic design was developed, directing drilling fluid upward from the bit base to enhance cooling and debris removal. The crown geometry was optimized for balanced cutting load and stable coring

Jingwei received a custom request for drilling in deep, abra sive formations with fractures and fault zones. Conventional core bits failed under these conditions due to overheating,poor chip evacuation, and reduced core recovery
