Rock Diamond Drilling Tool 9-1/2 Inch API Spec PDC Drill Bit

Rock Diamond Drilling Tool 9-1/2 Inch API Spec PDC Drill Bit

1 . Descriptions:

These specialized PDC drill bits are crafted with precision to tackle the challenges posed by exceptionally hard rock formations. Skilled professionals analyze the specific rock composition, hardness, and other geological factors to determine the ideal design parameters.

The key element of a PDC drill bit is its cutting structure. It consists of carefully positioned and strategically shaped polycrystalline diamond cutters. These cutters are created by subjecting diamond crystals to high pressure and temperature, resulting in a super-hard material capable of efficiently cutting through rock.

The design of the cutting structure takes into account factors such as cutter density, cutter size, and cutter profile. The density refers to the number of cutters per unit area, while the size and profile of the cutters are optimized to balance cutting efficiency and durability.

Additionally, the body material of the PDC drill bit is carefully selected to provide the necessary strength and durability required for demanding drilling operations. Tungsten carbide is commonly used due to its exceptional hardness and resistance to wear.

2. Specification:

Polycrystalline diamond compacts PDC bit in the Oil and Gas Industry PDC bits get their name from the polycrystalline diamond compacts used for their cutting structure. A PDC bit is a drill bit fitted with industrial diamond cutters instead of hardened metal teeth.

4 . Drill Bit PDC Cutters

Polycrystalline Diamond Composite (PDC) cutters are the main point of contact for a drill bit. PDC bits remove the rock mainly by shearing.

The PDC cutters are exposed to a lot of heating and cooling down the well, a very challenging environment.

PDC cutters that have lower thermal degradation and more thermal stability generally achieve higher ROP and increased wear resistance. So, optimizing the cutter is important.

5. PDC Drill Bit Nozzles

PDC Drill bit nozzles help clear the cutting area and cool the Polycrystalline Diamond Composite (PDC) cutters.

Effective placement of these nozzles along with the angle they are set at plays a critical role on how efficient the drill bit performs.

Fluid channels also complement nozzle placement to improve the clearing of cuttings.

6. Steel Body PDC Bits

The steel body of a PDC (Polycrystalline Diamond Compact) bit is the opposite of a matrix body. It is designed to withstand high impact loads but lacks the protective features found in matrix bodies. Steel bit bodies offer excellent strength and ductility, making them highly resistant to impact. In comparison, steel bodies are significantly stronger than matrix bodies.

One notable advantage of steel bits is their ability to be rebuilt multiple times. When cutters become worn or damaged, they can be easily replaced. This feature is particularly beneficial for operators working in low-cost drilling environments, as it allows for cost-effective maintenance and prolongs the lifespan of the drill bit.

PDC drill bits differ from roller cones in that they have one-piece bodies with no moving parts. The fixed cutters on PDC bits efficiently shred the rock, enabling the bit to operate at higher rotation speeds. This characteristic makes PDC bits well-suited for consolidated formations, where they can deliver enhanced drilling efficiency.

Suzhou Energy Tool Co., Ltd . (short for “ENG ” ) is a high-tech company formed by a group of drill bit experts with over 20 years of work experience in the world's top oil service companies. ENG has cooperated with many research institutes at home and has formed an advanced technological system based on market-oriented and continuously promoting technological innovation and product improvement. ENG‘S bits production lines are equipped with 5-axis machining centers, Modern lathes, and FMS (Flexible manufacturing system ) and can produce matrix body and steel body PDC bits from 3-1/4” to 26” in diameter.

ENG has been keeping on producing high-quality products to meet the buyer diffferent requirement of different drilling well and rock fromation . The company’s QMS has been award API, ISO 9001 certification for many years. ENG has Obtained 21 patents by Chinese government .On the products Research and Development, ENG has built the basis of 3-dimensional CAD and PDM (Product Data Management ), can technically control the whole process of product manager, so that the product development can be done in a fast and precise manner to maximally meet the time and function requirement of the market for product lifecycle management.

ENG developed different performance series PDC cutters for PDC bit to meet different drilling applications and drilling requirements of different formations. Some PDC Cutter is imported from the USA Or Europe. ENG's advantage is high product quality, short delivery time, small lot, and multi-types. The products have been exported to over 10 countries Such as the USA, Australia, Indonesia, Thailand, Malaysia, Indonesia, Argentina, and so on.
