Tungsten Carbide Tricorn Bit

Introduction

Tungsten carbide tricorn bit fixed in drill by chunk, and it has special triangular structure design, which has been widely used in rock and oil drilling fields.

Types

From the mechanism of rock drilling, it can be specifically divided into:
1. Cutting drill (by cutting action): polycrystalline diamond blade drill bit (PDC), thermal stability of polycrystalline diamond drill (TSP);
2. Punching drill bit (by impacting and crushing effect): different types of cone bit;
3. Abrasive drill (by grinding action): natural diamond drill bits, impregnated diamond bits.

Factors

1. Formation: mechanical properties of the rock formation, formation heterogeneity, graphic integrity, deflecting formation characteristics, depth, formation temperature;
2. Drilling mode: determines the speed of rotation;
3. Orbit control: angle building, angle holding;
4. The size of well;
5. Geology design requirements: such as cuttings logging, coring.
