Description
Technical field
The present invention relates to a kind of field of drill, specifically with the high speed bit of damping performance.
Background technique
Rock bit is a kind of most popular drilling bit.Cutting tooth alternately contacts shaft bottom when rock bit works,
Broken rock torque is small, and cutting tooth and shaft bottom contact area are small, higher than pressing, and is easy to wedging stratum；Work edge total length is big, thus phase
It is worn to reducing.Rock bit can adapt to a variety of stratum from soft to hard.A kind of work of the rock bit as drilling rock stratum
Tool has been widely used, and significantly improving for bit performance directly reduces drilling cost, and especially last decade progress is most fast.It uses
Two performance indicators of service life and drilling speed, they finally determine that drill bit influences the degree of drilling cost.Improve the rate of penetration of drill bit
Be to reduce the effective way of drilling cost with service life, there is a data confirmation, the improvement of drilling speed than bit life improvement to drop
The influence of low drilling cost is bigger, and wherein the improvement of bit cutting structure is to improve the rate of penetration most straightforward approach of drill bit.
Since some time, people focus primarily upon main cutting toothing to the improvement of cutting structure, such as in hard alloy toothing
Aspect, people successively invented chisel teeth, scoop chisel insert, push up partially scoop chisel insert, etc. abrasion tooth etc..People gradually recognize gauge
Structure also has larger impact to drill bit rate of penetration and service life, especially requires tool in the drill bit that high angle hole and horizontal well are applied
There is reasonable gauge structure, many novel gauge structures are studied to developed and be applied in rock bit and achieve well
Effect.But the anti-seismic performance of rock bit is bad at present, has to be developed.
