Product Overview
Description
Fixed PDC cutters
Product Description
Application:
PDC have high hardness, wear resistance and impact resistance, are widely used for industries include:
- oil/gas well drill bit,
- rock drill bit
- water well drill bit
- coal mining bit
- diamond tools for cutting, grinding, polishing.
For drilling, total penetration depths range from 100 meters to 10000 meters.
Production details:
PDC cutters are made using a combination of high heat and high pressure. Man made diamonds can be grown in 5-10 minutes. Because of this diamond content, a fixed cutter bit may also be known as a diamond drill bit.
Cutters are made from a carbide substrate and diamond grit. High heat of around 2800 degrees and high pressure of approximately 1,000,000 psi forms the compact. A cobalt alloy is also present and acts as a catalyst to the sintering process. The cobalt helps bond the carbide and diamond.
During the cooling process, the tungsten carbide shrinks at a rate of 2.5 times faster than the diamond. So the internal stress controlling is very important.
| TKD-G Series PDC oil cutters | |
| Application: | Medium quality PDC cutters for downhole tools and bits that require exceptional backup, gauge, updrill, reaming or stabilization applications. also for geotechnical drill bit cutters at drilling depth below 750 meters. |
| TKD-M Series PDC oil cutters | |
| Introduction: | Medium standard PDC cutters-good performance with medium impact and abrasion resistance. |
| Features: | Medium standard PDC cutters show better features with wear-resistance and impact-resistance, especially for wear-resistance, almost double performance than old generation items. |
| Application: | Suitable for medium hard(8-12 grade) oil/gas field drilling formations, very popular for simple drilling formations, single interbeded layer like (5-10 meter) can be allowed. Drilling area: 0-4000 meters. |
| TKD-S Series PDC oil cutters | |
| Introduction: | Senior PDC cutters- good performance with high impact and abrasion resistance. |
| Features: | From aspects of wear-resistance, impact-resistance, thermal stability, our Senior cutters all perform very well which can compete with foreign brand of cutters like US synthetic , E6, NOV etc. |
| Application: | Suitable for medium hard and hard(8-15 grade) rock mixture formation oilfield drilling on land and offshore drilling in the deep sea, especially suitable for high abrasion with interbeded layer(20-50meters allowed) formation deep drilling from 3000-6000 meters. |
