Structure features and applications of the bit:
1. Bit profile is optimized and is suitable for drilling soft to medium formations.
2. Cutting structure is force balanced, bit blade is asymmetrically designed, and spiral blade and spiral gage are also designed so that the load on bit is balanced which resulting better stability of the bit.
3. Multiple types of high performance PDC cutters are strategically arranged on bit for improved service life of the bit.
4. Shock absorbers are designed to make the bit capable of drilling through formations with hard stringers.
5. Hydraulic system of the bit is optimized using dynamic flow pattern simulation technology to enhance cleaning and cooling effects of the bit to effectively prevent bit from balling.
6. Erosion on bit surface is effectively prevented by utilizing hardfacing material of highly erosion resistant and applying advanced base metal enhancement technology.
7. Ports on bit are also optimally designed to prevent erosion of water courses inside the bit.
PDC bit Polycrystalline diamond materials, for use in polycrystalline diamond compact (PDC) bits, are one of the most important material advances for oil drilling tools in recent years. Fixed-head bits rotate as one piece and contain no separately moving parts. When fixed-head bits use PDC cutters, they are commonly called PDC bits. Since their first production in 1976, the popularity of bits using PDC cutters has grown steadily, and they are nearly as common as roller-cone bits in many drilling applications.
PDC bits are designed and manufactured in two structurally dissimilar styles (Fig. 1 and Fig. 2):
The two provide significantly different capabilities, and, because both types have certain advantages, a choice between them would be decided by the needs of the application.
