The Advantages of Using a Tri Cone Over Other Drill Bits
1)There is a Tri Cone suitable for any rock formation
2) Tricone bit is versatile and can handle changing formations
3)Tri Cones are reasonably priced, long lasting and have an efficient drilling rate
4)Tricone is that the roller cones have high end sealed bearings; extremely high quality tungsten carbideand diamond gauge protection throughout the drill bit as well as skirt tail hard facing and optimized hydraulics. These roller cone drill bits are designed to go to extreme depths in extreme conditions and in situations where they cannot fail.
Due to impact, crushing and shearing rock breaking when roller cone rotates, the contact area between cone and bottom hole is small, the specific pressure is high, the working torque is small, and the working blade has a large total length and can be suitable for rock of various kinds.
what is the working principle of tricone drill bit
Tricone bits rely on the impact of the cone on the formation, crushing and sliding shear to crush the rock.
The bit are widly used Water well . Oil well , Gas well . Pile Fundation etc field
