1,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 stablity of the bit.
2) Main cutter is high performance PDC cutter 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 systems of the bit is optimized using dynamic flow pattern simulation technology enhance cleaning and cooling effects of the bit to effectively prevent bit from balling.
