What factors affect the life of a PDC drill bit?

These following factors may affect the service life of PDC drill bits:

1. Stratigraphic conditions:

The hardness and abrasiveness of the rock can cause wear and tear on the drill bit.

2. Drilling parameters:

The life of the drill bit can be affected by unreasonable settings such as rotational speed, drilling pressure, etc. 3.

3. Drill bit quality:

Including material, manufacturing process, etc.

4. Cooling lubrication:

Inadequate may lead to overheating and accelerated wear.

5. Operating techniques:

Incorrect operation may damage the drill bit.

6. rock chip discharge:

Clogging will increase the load on the drill bit.

7. shock load:

May cause premature damage to the bit.

8. drilling fluid performance:

Directly affects bit life.

9. Drill bit compatibility:

Mismatch with drilling rigs and other equipment will affect the effectiveness of use.

10. Daily maintenance:

Improper maintenance will shorten the life of the drill bit.

To extend the life of a PDC drill bit, you need to consider all these factors and take appropriate measures.
