Product Description

Great Made Bi-center Bits features :

Engineered Cutting Structure

Bi-Center Bits developed using Great Proprietary design software , to ensures cutting structure optimization for specific applications . This bit behavior in different rock type during a simulated driling process.

This tool also evaluates cutter wear as result of friction and heat transfer .Using Appropriate rock geology and mechanical properties, also performs sensisitivity analysis for various drilling parameters (WOB and RPM ) to evaluate their effects on ROP ,cutter wear ,bit vibrations and footage drilled.

High Performance Cutters from Great drill bits factory

Application-specific PDC cutters incorporating advance carbide interface geometry (CIG) and material are used.

Diamond Grades are selected ,analyzed and prepared to maximize abrasion resistance .

Hydraulics

Bi-center Bits go through elaborate computational fluid dynamics evaluation to identify and eliminate possible stagnation zones . During this process, bit and bottom hole cleaning are optimized to enhance bit performance .

This sophisticated process improves cleaning efficiency , cutter cooling and ROP .
