The Structural Characteristics of Tricone Roller Bits

The structural characteristics of the tricone roller bit

Embedded teeth tricone roller bit adopts high-toughness hard alloy teeth, optimized design of tooth rows, tooth numbers, exposed tooth height, and the shape of alloy teeth, fully exerting the excellent cutting ability of the embedded tooth bit. The steel tooth bit surface is coated with new welding material, which not only maintains the high mechanical drilling speed of the steel tooth bit, but also improves the cutting tooth life of the bit.

The tricone roller bit adopts a floating bearing structure, and the floating component is made of a new material with high elasticity and high temperature resistance, and the surface is treated with solid lubricant. The tricone roller bit adopts a new type of lubricating grease that can withstand high temperature of 250°C and has high wear resistance. It can reduce the temperature rise of the friction surface while reducing the relative linear velocity of the bearing pair, and can improve the bearing life and stability of the bearing under high drilling pressure or high rotation speed drilling conditions.

The tricone roller bit adopts metal sealing. The metal sealing is made of a specially designed metal sealing ring as the axial dynamic sealing of the bearing. Two highly elastic rubber energy supply rings are respectively located in the tooth palm and tooth disc sealing areas as static sealing. The optimized sealing compression amount ensures that the two metal ring sealing surfaces are always in good contact.

It adopts a fully rubber-made oil storage bag that can limit the pressure difference and prevent drilling fluid from entering the lubrication system, which provides good lubrication for the bearing system. The steel balls lock the tooth disc to adapt to high rotation speed.

It adopts a new type of high-temperature resistant and wear-resistant lubricating grease that can withstand high temperature of 250°C.

The embedded tooth bit adopts high-strength and high-toughness hard alloy teeth, and optimally designs the number of tooth rows, tooth numbers, exposed tooth height, and unique shape of the alloy teeth, fully exerting the high wear resistance and excellent cutting ability of the embedded tooth bit. The steel tooth bit surface is coated with new wear-resistant material, which not only maintains the high mechanical drilling speed of the steel tooth bit, but also improves the cutting tooth life of the bit.

Tricone roller bit is an important tool for oil drilling

The performance of the tricone roller bit directly affects the drilling quality, drilling efficiency, and drilling cost. The design of tricone roller bits is mostly based on practical experience, combined with trial and error methods, and repeated design and calculation, so the design accuracy is low, the cycle is long, and it is difficult to improve the design quality. Furthermore, only one bit can be designed at a time, resulting in low efficiency.

The tricone roller bit is one of the most widely used drilling bits, with the characteristics of wide adaptability to formations and high mechanical drilling speed. The tricone roller bit is composed of more than twenty kinds of components such as cutting structure, bearing structure, locking element, oil storage sealing device, and nozzle device.

The good structural characteristics of the tricone roller bit can promote the generation of good features and usage, and contribute to its application in the drilling industry, playing a role and making contributions in drilling and exploration.
