Rock Breaking Mechanism and Experimental Research on Axial Tilt PDC Bit Tool
Academic Journal of Engineering and Technology Science, 2021 PDC bit has poor adaptability in soft and hard staggered, gravel-bearing and other heterogeneous layers and hard formations. The problem of easy pre-damage of the cutting teeth of the bit has not been solved yet. A shaft-tilted PDC bit tool is proposed. The most obvious feature of the tool is that the bit body is designed as an "axial-tilted" structure,
