Bit type | IADC Code | Applicable formation | Cutting structure | Normal WOB KN/mm(bit dia.) | Rotary Speed(rpm |
THJ517G | 517 | Soft with low compressive strength and high drillability,such as shale,clay,sandstone and soft limestone,etc. | Large radius offset crested scoop compacts in inner row,wedge compacts in outer row,high compact exposure and inequable spaced compacts arrangement. | 0.35~1.05 | 240~50 |
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.
