Product Details
Oilfield Drilling Reamer Tool 12-1/8 Inch 3080mm PDC Downhole
Assembly
Description :
Drilling performance is improved while borehole quality is
increased when underreamed. The variety of tools available assures
excellent performance in every application with operating
flexibility ranging from demountable cutters to cutters that
include milled teeth, tungsten carbide inserts, and polycrystalline
diamond compact (PDC) cutters.

Feature :
Fast drilling in a soft formation with a bit gauge that is limited
in length results in an uneven bore hole trajectory, which causes
bit bouncing, high torque, and drag.
By scraping the narrow, key-seating, etc. portions, the crocodile
reamer may smooth out the uneven well side.
The "full coverage"cutters cutting the unnecessary rocks in a
rounded manner
The radial vibration can be decreased by using specially shaped
cutters on the reamer supply series supporting point on the contact
between the BHA and hole wall.
Notable features :
We provide three PDC reamer kinds in various sizes:
- Assembler in BHA
- cutting the walls of the borehole
- Stabilizing the BHA while drilling.
- Replace the stabilizer and better than stabilizer.
Company Profile
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.
