Downhole Tools >> Steel Body PDC Bits

PRODUCTS>  


SPECIFICATION





Use high-quality steel as the base material of the bit, overlaying welded high performance wear resistant materials on surface of blade, and use the computer software to have overall three-dimensionally design of the bit , two-row asymmetric helical blade and long parabola crown structure. 

Cutting structure uses force balance design, the PDC composite pieces with different structure are arranged at different positions of the bit, and use the high-quality cutting tooth to maximize the equivalent density of the PDC composite cutting tooth, and effectively improve the offensive and anti-abrasive performances.

Apply the fluid dynamics analysis and numerical simulation technology into the design of the hydraulic flow field, and the maximum flute area and nozzle design makes the rock carrying effect and water jet assisted rock breaking effect of the jet to be optimal, and can wash and cool the bit better.







 It is suitable for medium- hard to hard formations with high compressive strength and abrasive property, such as mudstone, limestone, anhydrite, sandstone and so on.
