The Thermal Stability of Polycrystalline Diamond Compact Bit

DC bit
English: Polycrystalline Diamond Compact bit
Polycrystalline diamond compact Is one of the oil drilling industry commonly used drilling tools.
The advantage of PDC bit PDC
1, the force balance design make the drill with good guidance, fit downhole motor used in directional drilling, with smaller radial vibration;
2, patent PDC composite with different structure in different location of the bit of reasonable decorate a bit strong aggressive and abrasive resistance;
3, strong offensive designed to drill bit to get a high rate of penetration;
4, the dynamic flow field simulation technique is applied to hydraulic design, optimization, make the bottom hole flow field is beneficial to increase the speed of chip removal and balling.
5, because PDC drill bit materials mainly for casting tungsten carbide and diamond compact, so it has long life and high value.
PDC drill bit is mainly composed of drill bits, cutter, nozzle, gauge and connectors, etc. According to different bit body material, bit correspondingly divided into tire body drill bit and steel body. Tire body drill bit body is with different particle size of tungsten carbide powder and tungsten carbide powder and different ratio of impregnated metal into the design good mold without hitches impregnation sintered in high temperature and pressure. Steel drill bit body is body is made of alloy steel blank after machining. Bit body after sintering or processing good, above cutter welding, into the nozzle, and joint welding together became a bit again.
