About the choice of oil drill bits

In different use environments and working conditions, we need to consider multiple factors, and finally choose the right oil drill bit, because the oil used to drill oil when extracting oil, its working performance will directly affect the drilling quality, drilling efficiency and drilling costs
.

For example, different situations such as stratigraphic lithology, well section location, well body structure, etc.
will affect the use of drill bits, and we need to reasonably select and use drill bits
according to the parameters and conditions of drilling.
Different situations such as formation lithology, well section location, well body structure and so on will affect the use of drill bits, and the drill bits
should be reasonably selected and used according to the parameters and conditions of drilling.

The structure of the well body is different, and there are special requirements
for the size, model, and use of the drill bit.
Oblique drilling generally requires trimmed tooth shape or diameter conservation, and the use requires high speed and low drilling pressure
.
Collect information such as well body, drill bit selection, and use parameters, and determine whether the selection and use of drill bits is reasonable
according to the failure form.

Drill bit quality is the basis for using drill bits
.
Checking the quality, novelty and nozzle installation reliability before entering the well is the key
to drill bit use.
By checking the quality record of the drill bit before entering the well, it is possible to distinguish whether the quality or the use is causing the failure
of the drill bit.
Of course, choosing a good quality drill bit is also an important prerequisite
.

High-end carbide drill bits are more durable than ordinary products, why, because after some special processes, special ingredients, spray granulation, isostatic pressing, overpressure sintering, cryogenic treatment, etc.
, which can greatly improve the comprehensive performance of the alloy, so the hardness of the alloy products has good wear resistance and a longer
service life.
