IADC 5 SERIES DRILL BITS
The soft formation TCI tricone bits are used to drill low compressive strength, very soft formations. This bit maximized to use of both conical and chisel tungsten carbide inserts of large diameters and high projection. This cutting structure design, combined with maximum cone offset, results in high bit penetration rates. The deep intermesh of cutter rows prevents bit bailing in sticky formations.
Common fault analysis of Tricone bits
| Common fault | Fault description | Method |
| Early wear of the shirttail | Abrasive formations, bent drill rod, seriously worn stabilizer and insufficient air for drilling rate attained etc, are all the causes which result in premature shirttail wear. In this case, the configuration of cones is good and the amount of inserts wear is small. Shairttail wear can also allow the big roller bearings to fall out resulting in bit failure. | The designer should strength the shirttail with certain measures to increase the wear-resistance capacity of shirttails. |
| Early wear and loose movement of the bearing | Excessive weight on bit, insufficent air to clean the hole and/or cool the bearing, leads to bearings overheating due to improper cooling and poor cuttings removal can shorten the service life of bit bearing. | Reduce bit pressure and increase air pressure |
| Cutting structure failure | Excessive WOB or Rotation speed; Wrong bit selection; Cuttings blowing in bad conditions caused repeating crushing. | Correctly select operating parameters and rotary types for specific working conditions |
