22 Inch Roller Cone Drilling Bit

A tricone bit plays a vital role in the bottom hole assembly of drilling operations. This mechanical drill bit relies on its teeth to create friction and rotational motion, enabling it to effectively remove the rock surface while drilling. Its primary function is to harness the energy from the rotating drill string and mud supply, utilizing this force to facilitate the process of deepening the well.

Applications

• Geotechnical investigation
• Mining exploration & Probing
• Geotechnical instrumentation
• Geophysics

Bearing Types

• STANDARD OPEN BEARING ROLLER BIT:
On these bits the cones will spin freely. This type of bit has a front row of ball bearings and a back row of roller bearings.
• SEALED BEARING ROLLERS BITS
These bits have an O-Ring seal with a grease reservoir for bearing cooling. The seals acts as a barrier against mud and cuttings to protect the bearings
• JOURNAL BEARING ROLLER BITS
These bits are strictly oil/grease cooled with nose bearings, O-Ring seal and a race for maximum performance.


IADC Codes

First Digit 1, 2, and 3 designate STEEL TOOTH BITS with 1 for soft, 2 for medium and 3 for hard formations.
4, 5, 6, 7 and 8 designate TUNGSTEN CARBIDE INSERT BITS for varying formation hardness with 4 being the softest and 8 the hardest.

Second Digit 1, 2, 3 and 4 are further breakdown of formation with 1 being the softest and 4 the hardest.

Third Digit This digit will classify the bit according to bearing/ seal type as follows:
Standard open bearing roller bit Standard open bearing roller bit,
air-cooled Standard open bearing roller bit with gauge protection which is defined as carbide inserts in the heel of the cone Sealed roller bearing bit Sealed roller bearing bit with gauge protection Journal sealed bearing bit Journal sealed bearing bit with gauge protection.

Fourth Digit The following letter codes are used in the fourth digit position to indicate additional features: A. Air Application R. Reinforced Welds C. Centre Jet S. Standard Steel Tooth D. Deviation Control X. Chisel Insert E. Extended Jet Y. Conical Insert G. Extra Gage Protection Z. Other Insert Shape J. Jet Deflection

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.
