How to choose rock drill bits

In different use environments and working conditions, we need to take into account many factors, and then choose the appropriate rock drill bit, because when it is used for drilling oil, its working performance will directly affect the drilling quality, Drilling efficiency and drilling costs.

The type and hardness of the rock being drilled is the key factor. Different rock formations require different types of bits.

For example, soft rock may require a bit with a concave appearance and a small tooth size, while hard rock may require a bit with a large profile and multiple selection of ball teeth.

Consider a specific industry or application, such as mining, quarrying or construction.

Drill bit selection may vary, depending on whether the drilling is for exploration, mining, or other purposes.

Different wellbore structures have special requirements for the size, model, and purpose of the drill bit. The inclined drill generally requires a trimming tooth shape or a diameter-gauge structure, and the use requires high rotation speed and low drilling pressure. Collect information such as wellbore, bit selection, use parameters, etc., and determine whether the selection and use of the bit is reasonable according to the failure mode.

The quality of rock drill bit is the basis for using the drill bit. Checking the quality, freshness and nozzle installation reliability of the drill bit before entering the well is the key to the use of the drill bit. Check the quality record of the drill bit before going into the well, you can distinguish whether the failure of the drill bit is caused by quality or use. Of course, choosing a good quality drill bit is also an important prerequisite.

Zhuzhou Jinxin's drilltools are more durable than ordinary manufacturers' products. Why, because our products have undergone some special processes, special ingredients, spray granulation, isostatic pressing, overpressure sintering cryogenic treatment, etc., which can greatly improve the synthesis of the alloy. performance, so the hardness and wear resistance of our alloy products exceed the national standard, and the service life is longer.
