Tricone Steel Tooth Seal Bearing 17 1/2"/ Steel Bit Quality Chisel Rock Drill Bits

Introduction

In challenging situations, Tricone drills are easy to control, providing more options in terms of torque and drill weight. Melamine drill bits are also more suitable for various rock formations, especially hard rock formations. The role of a single roller on three drill bits helps to break the rock, making it significantly more flexible in the range of strata that can be used by one drill bit.

Operational principle

1) The speed of the drill bit is the speed of the rotary table or downhole power drilling tool. When the drill bit rotates, the cone also rotates around the axis of the drill bit. The linear velocity of each row of teeth on the cone rotating around the axis of the drill bit is different, and the linear velocity of the outer row of teeth is the highest.

2) The rotation of the drill bit is called rotation when the cone rotates counterclockwise around the tooth palm axis. The rotational speed of the cone is determined by the rotational speed of the drill bit and is related to the influence of the teeth on the bottom of the well.

3) The longitudinal vibration (axial vibration) of the drill bit impacts and changes the position of the breaking wheel center, causing the drill bit to reciprocate up and down along the axial direction. This is the longitudinal vibration of the drill bit, which is related to the structural parameters of the drill bit such as tooth height, tooth pitch, and lithology. The amplitude of soft formations is small, while that of hard formations is large. The vibration frequency is proportional to the number of teeth and cone speed.

4) The sliding shear fracture effect of a drill bit requires different types of rock to be broken, which is determined by the structural parameters of the drill bit. In soft formations, the slip of the drill bit is relatively large, while in hard formations, it should be as small or non slip as possible.

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.
