How to choose the type:
shallow well, mainly consider the drilling speed and preventing the mud pack.
deep well,mainly consider the bit footage
When out of the well the outer cutter is broken heavily, should be selected with gage bit
In the ease of deviated section should use small and short cutter bit
In the selection of insert button bit, should use the wedge-shaped cutter
Diamond limestone, appropriate uses double bevel gear, projectile shape tooth bit
Shale more or drilling fluid density is larger, should be selected with a larger amount of slip drill
The formation of limestone, sandstone, should choose smaller slip bit
In drilling hard and high abrasive stratum, appropriate uses ball tooth, double cone tooth head.
