Diamond Drill Bit 6-1/2 Inch PDC Rock Bit Of Hard Rock Drill Bit

Diamond Drill Bit 6-1/2 Inch PDC Rock Bit Of Hard Rock Drill Bit

1 . Descriptions:

PDC rock drill bit is one type of fixed cutter Bit . Suely ,PDC Rock bit is diamond cutting elements to fragment the rock . Then the Diamond

bit are main types of polycrystalline diamond compact (PDC), natural diamond (mills), and diamond impregnated bits.

According to the International Association of Drilling Contractors (IADC), the Fixed-cutter PDC drill bit classification composed of four characters that designate:

• PDC Drill Bit Body material.
• PDC Drill Bit Cutter density.
• PDC Drill Bit Cutter size or type.
• PDC Drill Bit profile

All of our PDC Drill bits are fit for API standard and used in the drilling Industry.

The PDC drill bits size 3~22inch with 3~9Blades are available. And different classification cutter are optional according to your budget .

4 . PDC Drill Bit PDC Cutters

Polycrystalline Diamond Composite (PDC) cutters of PDC Drill Bit 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.

What is the PDC drill bit Cutter size or type ?

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

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

Steel bodyof PDC Drill 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 of PDC Drill bits are considerably stronger than matrix bodies.

A beneficial feature of steel body of PDC Dril 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 pursuing producing high-quality products with relevant inspections and tests. The company’s QMS has been certified by API, ISO 9001 for many years. ENG has 8 patents granted in China. 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.
