Tricone Drill Bit of Water Drilling Well

Tungsten Carbide Insert (TCI) bits serve as indispensable tools for drilling operations in middle to hard rock formations, presenting a versatile range of carbide inserts meticulously designed to address the varying hardness levels of rock encountered during drilling endeavors. These inserts come in diverse shapes, including spherically shaped inserts tailored for exceptionally hard rock formations and conically shaped inserts optimized for softer rock materials.

The selection of carbide inserts plays a pivotal role in determining the efficiency and effectiveness of the drilling process, as different rock formations demand specific insert configurations to achieve optimal results. The number of rows of inserts featured on TCI bits is directly correlated with the nature of the application and the desired hole size, allowing for customizable configurations that cater to specific drilling requirements.

TCI Tricone Bits feature :

Tungsten carbide inserts, excel in drilling operations in middle to hard rock formations. These bits offer a variety of carbide inserts, including spherically shaped inserts for very hard rock and conically shaped inserts for softer rock, catering to the diverse hardness levels encountered during drilling endeavors.

The number of insert rows directly correlates with the application type and hole size, ensuring customizable configurations for optimal drilling performance. Operators can choose between open and sealed bearings, along with three shirttail protection options, enhancing durability and performance in challenging drilling conditions.

Bearing Types

There are primarily three types of Open and seal bearing designs used in tricone drilling bits:

• STANDARD OPEN BEARING ROLLER BIT:

On these bits the cones will spin freely. This type of bit has a front row of ball bearings and a back row of roller bearings.

• SEALED BEARING ROLLERS BITS

These bits have an O-Ring seal with a grease reservoir for bearing cooling. The seals acts as a barrier against mud and cuttings to protect the bearings

• JOURNAL BEARING ROLLER BITS

These bits are strictly oil/grease cooled with nose bearings, O-Ring seal and a race for maximum performance.

What we should be pay attention on choosing the tricone drill bit ?

• IADC code passport
• TCI & Steel tooth options
• Additional tungsten carbide inserts on heel rows
• Tungsten carbide coating on cone bodies
• Diamond coated tungsten carbide inserts on the gauge of the cones
• Tungsten carbide inserts on the shirttail of the legs
• Additional central nozzle for cleaning cones

The tricone feature is that they come with their own passport as below :

• The specification of the cones
• The recommended drilling parameters to get the best performance out of the bit:
• Bit weight
• Rotation speed
• Flushing volume
