PDC Introduction
PDC (Polycrystalline Diamond Compact) is composed of diamond micron powder and cemented carbide liner than are sintered toghether under high temperature and high pressure. It not only has the high wear resistance that diamond has, but also has the high impact-resistance toughness.
Characteristics
1 Using PDC as the main cutting components;
2 With the excellent wear ability and impact toughness of the PDC;
3 High drilling speed;
4 Improving the drilling efficiency and reduced labor intensity;
5 Widely used in warious of different fields, mining, hydrology, subterranean, piling, water well drill and oil well drilling. It has high efficiency and strong wear resistance for drilling.
Advantage
1 Force balance design gives the bits a good direction quality. Therefore it can be applied in the direction drilling by reducing the journal shake through coordinating with down-hole motor.
2 The reasonable allocation of Polycrystalline Diamond Compact different structure in bits different place equips bits with stronger drilling performance and abrasiveness.
3 The bits can attain higher drilling speed by the strong impact resistant design.
4 The dynamic flow field imitation technology are applied in the water conservation, optimized down-hole flow field, improving the junk discharging speed and preventing balling.
5 It can get the long service life and high value because the material of PDC cutter bits consist of casting tungsten carbide and polycrystalline diamond compact.
Specification
size 27mm, 28mm, 32mm, 42mm
