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 Asymmetric double teeth straight blade, medium parabolic crown, long gauge shape structure. Cutting structure design using the force balance, cutters rational arrangement to different structures in different locations of the drill, drill effectively improve the offensive and anti-abrasive, a substantial increase drilling speed, the application of fluid dynamics analysis and numerical simulation of flow field analysis techniques to the design of hydraulic nozzle angle and position of numerical simulation using finite element analysis method, so that the effect of jet carrying rocks and water jet assisted rock to achieve optimal results.
 

Suitable for low compressive strength homogenous laminated formations, such as clay, marl, lignite, sandstone and so on.
