Description
Tricone Drilling is a mechanical drill bit located in the bottom of the well assembly. Tricone Drilling is mainly used for drilling into various formations from soft, medium to hard. They are particularly suitable for hard rock formations. These drills are very reliable in ever-changing rock conditions.
Ground tooth Tricone bits are used in soft rock formations. The protruding teeth are widely spaced to prevent clogging by material as they cut into the surface material. Tungsten carbide insert (TCI) triangular bits are used in medium to hard rock formations. These bits are designed with smaller teeth that are more closely aligned. Higher drilling speeds are achieved when the formation is hard and the TCI can withstand the heat generated by these conditions. Mud is pumped into the drill column and discharged through the tri-cone bit to keep the bit free of rock chips and to move these chips back to the surface.
Tricone Drilling can be made from diamond or other metals, but tungsten carbide is one of the most popular materials. Sintered tungsten carbide tools have high wear resistance and can withstand higher temperatures than standard HSS tools.
1. Grand Tungsten carbide insert tooth sealed and gage protection journal bearing, hard faced head bearing surface. Cone bearing inlaid with friction reducing alloy and then silver plated. The load capacity and seizure resistance of the bearing is greatly improved.
2. O- ring seal is made of the more wear resistance high saturated Buna-N with the section and precisely designed sealing flange in the cone sealing area increased the reliability of the seal.
3. The bit bearing is ball which can be applied to high rotary speed drilling.
4. All rubber compensator is used which can provides the bearing system with good assurance of lubrication.
5. Grand new type of grease that can sustain high temperature up to 250C is utilized.
6. Grand high wear resistance and excellent cutting ability of the insert bit are given full play by using carbide compacts of high strength and high toughness in combination with optimized compact numbers and rows, the exposure height and special shaped compacts.
7. Meet strictly of API standard.
8. Grand is professional manufacturer of TCI tri-cone bits, steel tooth tri-cone bits and PDC bits.
9. High quality, reasonable price and best service.
10. Delivery in time.
11. Good feedback of the clients.
12. Grand drilling bits can be used for all kinds of water well, oil field, underground, construction, geothermal well,etc.
