IADC517/537 Tricone Pilot Reamer Diamond PDC bit Hole Opener For Oil Rigs
Introduction
PDC or "PAX" core bits utilise large cylindrical shaped cutters
that consist of a layer of micron-sized synthetic diamond particles
mounted onto a tungsten-carbide backing substrate (PDC =
polycrystalline diamond compact).
The technology was originally developed for oil drilling bits. PDC
core bits have proved to be exceptionally cost effective for
geotechnical drilling.
PDC core bits have extremely fast penetration rates and a very long
working life. The cutters are extremely tough and can core
formations such as hard limestones with occasional bands of harder
rock such as ironstone.
The cutting action is extremely aggressive and a large volume of
cuttings are produced requiring good volumes of flush to clear the
hole and prevent blocking.
Recommended for coring soft to medium hard formations, with water,
air, mud or foam as the flushing medium. Ideal for air flush
applications where a high rate of production is required.
The size, number and layout of the cutters can be varied to suit
the rock hardness, abrasivity and other details of the application
PDC drill bit used to penetrate the degassing hole, drain hole, and grouting hole of coal mine, water canservancy and hydropower, road construction, bridge and building.
Description of PDC drill bit
- Suitable for soft, medium and hard formations.
- Super strong material promotes gauge wear resistance to provide long bit life.
- The cutter’s back rake has been unique design, reducing the bit torque and increasing aggressiveness.
- Cuttings removal and bit cooling for bits are optimized by matching the volume of rock removed by the cutter on each blade with the proportional fluid flow.
Different types of PDC drill bit
- for Oil well drilling:PDC Coring Bits, PDC Drill Bits.
- for Mining:PDC Coring Bits, PDC Drill Bits.
- steel body PDC bit.
- matrix body PDC bit.
