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.
