Model:2-7/8"~17-1/2"
steel body pdc bit
diamond pdc bit
Cangzhou Great Drill Co., Ltd is located in North China Oil Field, Junziguan industrial zone Hejian,
north Beijing, east of Tianjin Port. We can supply pdc bit, diamond pdc bit, diamond core bit,
matrix body pdc bit, steel body pdc bit, impregnated core bit. Our diamond bits are named as
Great, with specifications ranging from 2-7/8" to 17-1/2". All our products have passed
ISO9001 certification.
Product Description:
1. Cutting structure is force balanced and bit blade is asymmetrically designed so that the load on bit is balanced that
resulting better stability of the bit.
2. Main cutter are high performance PDC cutters to insure service life of the bit while improving ROP.
3. Cutter exposure is optimized to insure the bit can achieve higher ROP is soft to medium formations.
4. Shock absorbers are designed to make the bit capable of drilling through formations with hard strigers.
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.
