Product Q&A

Q:What is the difference between near-bit and string stabilizers?

Near-bit models are installed directly above the drill bit to ream simultaneously and prevent deviation, ideal for directional wells. String models are mounted among drill collars to centralize the string and repair undergauge sections, mostly used for vertical wells.

Q:What raw material is used for the stabilizer body?

We use forged AISI 4145H Mod alloy steel for all tool bodies. Complete quenching and tempering heat treatment ensures high torsion resistance and impact toughness for deep wells and hard formations.

Q:What is the function of hardfacing on tool blades?

Tungsten carbide hardbanding is welded on contact surfaces of blades. It greatly improves abrasion and erosion resistance, extends downhole service time, and reduces round trips to lower total drilling cost.

Q:How to decide whether to use a stabilizer or PDC reamer?

Choose a stabilizer if you only need to centralize the drill string and control deviation. Choose a PDC reamer if you need to enlarge the hole diameter and repair undergauge sections. They can be combined in one BHA for better performance.

Q:Do you supply crossover subs for stabilizers and reamers?

Yes, we can provide matching crossover subs, lift subs, jars, and other bottom hole assembly tools for one-stop procurement.
