Diamond PDC Drill Bit 17-1/2 Inch 7 Blades API Bit Of Rock Drill Tool

Diamond PDC Drill Bit 17-1/2 Inch 7 Blades API Bit Of Rock Drill Tool

1 . Descriptions:

PDC drill bits are highly efficient tools used for drilling through sedimentary rock formations like shale, sandstone, dolomite, and limestone. They employ a shearing or scraping action to penetrate the rock effectively.

PDC bits are known for their exceptional rigidity and are made by combining layers of synthetic diamond with a carbide substrate under high temperature and pressure conditions. This manufacturing process ensures their durability and reliability in demanding drilling applications.

The International Association of Drilling Contractors (IADC) uses a four-character classification system to designate PDC bit properties, including body material, cutter density, cutter size or type, and profile. Our PDC drill bits meet API standards and are widely used in the drilling industry.

We offer PDC drill bits in sizes ranging from 3 to 22 inches with 3 to 9 blades. We also provide different cutter options to accommodate various budgets.

4 . PDC Drill Bit Cutters

Polycrystalline Diamond Composite (PDC) cutters are the main point of contact for a drill bit. PDC drill 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.

Accorrding to the Api ,the cutter size are as below :

1 indicates PDC cutters > 24 mm in diameter.

2 represents cutters from 14 to 24 mm in diameter.

3 indicates PDC cutters < 14 but > 8 mm. 4 is used for cutters < 8 mm.

5. PDC Drill Bit Nozzles

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

Steel body of PDC Bit is the opposite of matrix body. 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 or damaged cutters can be replaced rather easily. This is a particular advantage for operators in low-cost drilling environments.

Polycrystalline diamond compact (PDC) drill bits are different than roller cones in that they are one piece bodies with no moving parts. The fixed-cutters shred the rock, so the bit is able to operate with higher rotation speeds more efficiently in consolidated formations.

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.
