Oilfield Drilling Tool 8-1/2 Inch 3 Blades API Spec Diamond PDC Hole Reamer

Oilfield Drilling Tool 8-1/2 Inch 6 Blades API Spec Diamond PDC Hole Reamer

1 . Descriptions:

There are two types of PDC hole reamers: fixed and interchangeable. These polycrystalline diamond compact (PDC) drill bits are solid tools without any movable parts. The fixed-cutters on these reamers effectively scrape away the rock, allowing for more efficient operation at higher rotation speeds, especially in consolidated formations.

2. Specification:

Polycrystalline diamond compacts PDC bit in the Oil and Gas Industry PDC bits get their name from the polycrystalline diamond compacts used for their cutting structure. A PDC bit is a drill bit fitted with industrial diamond cutters instead of hardened metal teeth.

SPECIFICATION

Size : 8-1/4 inch (215.9mm)
Drill Body Type : Steel Body

4 . Drill Bit PDC Cutters

Polycrystalline Diamond Composite (PDC) cutters 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.

5. Drill Bit Nozzles

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 imp
