Use high-quality steel to make the base material of PDC bit, the surface of the blade weld high-performance wear-resistant materials,the use of computer software for the overall design of three-dimensional PDC Bit, double asymmetric teeth straight blade ,medium parabolic crown,long gage shape structure using force balance design,unique PDC cutter layout and positioning of the PDC bit to keep a sharp cutting edge in drilling, effectively inprove the offensive PDC BIT and drilling speed .The application of fluid dynamics analysis and numberical simulation of hydraulic flow fied analysis technology to design,help to improve chip speed drill and anti-balling capacity.
