Product Description

PDC drill bit with deep blade and long parabolic configuration, ensure optimal bottom hole flow pattern and anti-balling.

Anti-whil design improves ROP and enhance the drilling stability.

Arc blade and spiral gauge enhance the cutting capability and the drilling stabilization.

Medial cutter density design is suitable for soft to medial formations.

Introduction of PDC drill bit

♦ Steel body with hardening tungsten carbide surface(WC),make the drill bit both high strength and very strong abrasion
resistance.
♦ Dedicated PDC cutter can improve the life and shield the risk of complex formation drill not passed.
♦ Raw materials: Alloy steel with a special treatment, achieve better mechanical properties (Rp0, 2: 1200MPa; Rm: 1100 MPa)
♦ Low torque spiral design and software designed tooth reduce the cutting edge wear & increase life
♦ (no repair life up to 8300 M/pc).
♦ The unique parabolic crown-shaped design and tooth balance design keeps smooth drilling under high speed.
♦ (Speeds up to 30~40m/h.)
♦ The scientific drilling dynamic equilibrium design and hydraulic balance design make the drilling process more smooth.
♦ Authoritative API standard and ISO certification, quality and service will be better ensured.

Types of PDC Bits

1. Matrix Body PDC Bits
"Matrix" is a very hard, rather brittle composite material comprising tungsten carbide grains metallurgically bonded with a
softer, tougher, metallic binder. Matrix is desirable as a bit material, because its hardness is resistant to abrasion and
erosion. lt is capable of withstanding relatively high compressive loads, but, compared with steel, has low resistance to impact loading. Matrix is relatively heterogeneous, because it is a composite material. Because the size and placement of the particles of tungsten carbide it contains vary (by both design and circumstances, its physical properties are slightly less predictable than steel. Matrix-body PDC bits are commonly preferred over steel-body bits for environments in which body erosion is likely to cause a bit to fail. For diamond-impregnated bits, only matrix-body construction can be used.

2. Steel Body PDC Bits
Steel is the opposite of matrix. It can of withstanding high impact loads, but is softer and lacks protective features. The
strength and ductility of steel give steel-bit bodies high impact resistance. Steel bodies are considerably stronger than matrix bodies. A beneficial feature of steel bits is that they can easily be rebuilt a number of times because worn on damaged cutters can be replaced rather easily. This is a particular advantage for operators in low-cost drilling environments.

What Kind of PDC Bit is Suitable

 

Steel body PDC bit	These steel bodied bits have advanced hydraulics and forward advanced blades that significantly increase ROP. The bits are specially designed to increase productivity in sandstone and shale formations. They are customizable with flushing holes and fixed or adjustable nozzles,along with blade count and diamond cuter size configuration options.
matrix body PDC bits	The matrix body PDC bits provide a stronger wear resistance due to the matrix powder that is applied to the body. The matrix body style is able to withstands harder compositions,such as dolomite and limestone. Bits are fully customizable with flushing holes and fixed or adjustable nozzles, along with blade count and diamond cutter size configuration options.
