Product Description

High Precision 100% New Rotary Oil Well Tci Roller Cone Bits /tricone bit /tricone drill tci bit


 

Introduction

Air or drilling fluid allows the broken rock debris to survive in an upward annulus from the bottom of the hole. As the rotation continues, another tooth contacts the bottom of the hole and generates new rock debris, thus the process is continuous. High quality tungsten carbide blade (TCI) drill bits and milling tooth (MT) drill bits need to be designed to withstand high temperatures and long-term operation, while drilling through soft to superhard formations.

Features

 

1. The wear resistance of the cutting structure teeth is enhanced by high-quality tungsten carbide surfacing on the surface of the steel tooth drill bit teeth. Adopting new formulas and processes to improve the durability of high-quality hard alloy blades

 

2. The table structure is protected by multiple gauges and trimmed at the heel of the cone, while the insertion and surfacing of hard alloy at the tail of the shirt increase gauge retention capacity and bearing life.

 

3. The bearing structure has two thrust surfaces for high-precision sliding bearings. The ball locks the cone. Hard end bearing surface. The tapered bearing is embedded with antifriction alloy and then silver plated. Improved the wear resistance and anti snap resistance of the bearings.

 

4. High quality HNBR O-ring for sealing and lubrication, optimized sealing compression and bending sealing structure, improves sealing performance. The pressure compensation system and advanced lubricating grease greatly improve lubrication reliability.

 

5. Product application can achieve high drilling pressure in conventional drilling. By matching cutting structures with different tooth shapes, tooth densities, and tooth exposure heights, it is suitable for various formations.

Used in
Tri-cone bit is a decelerating bit. It is based on the fact that the speed of the cone is less than the speed of the bit. It is suitable for sidetracking of old wells and deepening of small boreholes under high speed and high drilling pressure.
