2. Introduction to the used tricone drill bit

The IADC codes of TCI tricone bits and steel tooth bits
Tricone bit Cutting structure:very long widely spaced ,chisel-shaped inserts and considerable
cone axis offset against center line of bit ensure very high penetration rate.To secure the bit from
diameter loss, the gage protection inserts have got shorter length and greater angle of the top.
Formations: long intervals of very soft poorly compacted shales ,sandstone, clays, salts and soft
limestones. Size and IADC available: 3 3/4" to 26" IADC415,435,445,417,437,517,537,617
TCI 437 soft formation tci tricone bits
The 437 tci bits are used to drill low compressive strength very soft formation tci bits maximize the
use of bothconical 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.
TCI 517 medium formation tci tricone bits
The 517 features aggressive chisel tungsten carbide inserts on the heel rows and inner rows this
design provides a fast drilling rate and added cutting structure durability in medium to medium hard
for mations the HSN rubber o-ring provides adequate sealing for bearing durability.
TCI 637  can be used to drill hard and abrasive forma-tions .wear -resistant tungsten carbide
inserts are used in the outer rows to prevent loss of bit gauge.maximum numbers of hemispherical
-shaped inserts are used in all rows to provide cutter durability and long life.
TCI 617 the tci 617 features robust chisel tungsten carbide inserts on the heel row and conical on
the inner rows .this design provides a fast drilling rate and added cutting structure durability in medium
to medium hard formations . the HSN rubber o-rin provides adequate sealing for bearing durability .

Steel tooth bit
The 114-117 soft formation tooth 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-resistent hard facing is used to control tooth wear. On the softest bit types this hard
facing completely covers the bit teeth.
The 127 medium - hard formation tooth bits
Used to drill high-compressive strength medium hard formations   short projection teeth with reduced
crest length are used in this series of bit designs durable hard facing is applied to reduce tooth wear.
Milled tooth bit specializes in designing, manufacturing, marketing and serving the high perform
-ance diamond bits and drilling tools used in petroleum industry
