Structure features and the applications of 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 gauge are also designed so the load on bit is balanced which resulting better stability of bit.
3. Multiple types of high performance PDC cutters is strategically arranged on bit for improved service life of bit.
4. Shock absorbers are designed to make the bit capable of drilling through formations with hard stringers.
5. Hydraulic system of bit is optimized using dynamic flow pattern simulation technology to enhance cleaning and cooling effects of bit to efficiently 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 is also optimally designed to prevent erosion of water courses inside bit.
