Drilling stabilizer- Three roller stabilizer is made from AISI 4145H alloy steel, implementation of API specification, threads can be cold rolled, copper-plating or phosphating.

The three roller stabilizer is an important tool for oil, gas and geology exploration drilling engineering to prevent well deflection. Drill collars,heavy weight drill pipe and lifting subs are tools matched with stabilizers.

Description

THREE ROLLER STABILIZER

 

A drilling stabilizer is a piece of downhole equipment used in the bottom hole assembly (BHA) of a drill string. It mechanically stabilizes the BHA in the borehole in order to avoid unintentional sidetracking, vibrations, and ensure the quality of the hole being drilled.

It is composed of a hollow cylindrical body and stabilizing blades, both made of high-strength steel. The blades can be either straight or spiralled, and are hardfaced for wear resistance.

Several types of drilling stabilizers are used in the oilfield today. While integral stabilizers (fully machined out of a single piece of steel) tend to be the norm, other types can be used, such as :

Replaceable sleeve stabilizer, where the blades are located on a sleeve, which is then screwed on the body. This type can be economical when no repair facilities are available close to the well being drilled and air freight has to be used.

We offer several options for IBS, in both alloy steel and non-magnet materials:

* Spiral Integral Blade Stabilizer;

* Straight Integral Blade Stabilizer;

* Non-Magnet Integral Blade Stabilizer;
