Complaint
Which is a matrix body PDC bit with double rows Asymmetric spiral five blades design, long parabolic crown and tapered blades with large TFA to improved hydraulic balance and stability. of PDC bit. Different strueture patent cutters are laid out at different location of the bit to ensure its high aggressiveness and long bit life .Effectively improve the rate of speed .Dynamic flow simulating technology is used for hydraulic design to ensure optimum bottom hole flow patters and anti-balling.Medium hard to hard formations with high compressive strength and abrasive ,such as Mudstone, Limestone, Anhydrite, Sandstone and so on.
