Product Description

We sale PDC and Tri-cone bit

In the drilling process, the drill bit is the main tool for breaking the rock, and the wellbore is formed by the drill bit breaking the rock. The formation of a wellbore is good or bad, and the length of time it takes is not only related to the characteristics of the formation rock being drilled and the performance of the drill bit itself, but also related to the degree of mutual matching between the drill bit and the formation . The reasonable selection of the drill bit plays an important role in increasing the drilling speed and reducing the comprehensive cost of drilling. The drill bit is one of the important tools for oil drilling. Whether the drill bit adapts to the nature of the rock and its quality plays a very important role in the selection of drilling technology, especially in terms of drilling quality, drilling speed, and drilling cost. With a huge impact, PDC bit is a rock breaking tool widely used in the oil and gas exploration and development industry today. It effectively improves mechanical drilling tools and shortens the drilling cycle.

Product Description

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.

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.
