[0015] Example
[0016] The content of the present invention is as follows:
[0017] (1) Adopt a thinking and design method to improve the wear resistance of the drill bit. While improving the wear resistance of the carcass, the gauge effect of the working layer of the drill bit is strengthened to achieve stable operation of the drill bit and balanced wear of the working layer to achieve improvement The purpose of drill life.
[0018] (2) On the basis of ordinary hot-pressed diamond drill bits, the thermally stable polycrystals are distributed and arranged in the working layer of the drill bit in a regular and orderly manner. Thermally stable polycrystals not only play the role of rock breaking, but also strengthen the wear resistance of the drill bit and the gauge effect, which effectively improves the stability and service life of the drill bit.
[0019] (3) To improve the wear resistance of the drill bit is not only the use of a matrix with high wear resistance, but often the use ...
