Borehole Drilling Tricone Roller Bit For Hard Formations
Description
Tricone bit is mainly used in oil well,water well, coalbed methane and geothermal well drilling engineering. Glorytek tricone bits are designed and manufactured according to the standard of oil drilling bit, which are long life, high drilling efficiency and low operation cost.
Structure
The tricone bit is composed of three cones and three tooth palms
assembled together and processed with some necessary functional
structures.
According to the structure, the tricone bit can be divided into:
bearing structure, cutting structure, cone tip and cone back
reinforcement structure, flow channel system, injection system, oil
storage pressure balance system and thread connection.
