The Advantages to Use Tricone BitsThan Other Kinds of Rock Bits
1) There is a tricone suitable for any rock formation
2) Tricone bits are versatile and can handle changing formations
3) Tri cones Are reasonably priced with long life and good rate of drilling
Steel Tooth Tricone Rock Bits IADC CODE---Formation |
IADC 114. 115.116.117 Soft formation
The 114-117 bits are used to drill low-compressive strength,soft formations. Long projection tooth lengths are used on high offset cones to provide the greatest penetration rates possible. Wear-resistant hard facing is used to control tooth wear.On the softest bi types this hard facing completely covers the bit teeth |
IADC 124.125.126.127 Medium formation
Medium formation with high-compressive strength and high drillability. Such as sandstone, anhydrite, salt, shale, limestone.
|
IADC 134.135.136.137 Medium soft formation
Formations with low compressive strength, such as shale, anhydrite, sand and so on for soft formation
|
IADC216.217 Medium hard formation
The 216-217 bit are always used to Soft to medium formations with low-compressive strength, such as shale, anhydrite, sand and so on for soft formation.
