API Integral Spiral Blade Stabilizer/Drilling stabilizer/Near bit stabilizer/String stabilizer

Specifications

Drilling stabilizer is an important tool to control hole deviation in petroleum and gas exploration drilling process. The types of it can be devided into drill string type and near bit type. At present, we developed HF3000 and HF5000 type stabilizer, which are widely used in international drilling operation.

1. Integral Spiral Blade Stabilizer: It is devided into integral 3-spiral blade stablizer, integral 4-spiral blade stablizer. There are four kinds of abrasive resistant materials on the working surface of stabilizer: Insert tungsten carbide buttons, insert diamond compound body, low temperature welding tungsten carbide pieces, hardfacing electrode on the surface and so on.

2. Integral Straight Blade Stabilizer: Integral 3-straight rib stabilizer, integral 4-straight rib stabilizer, and Integral multistraight
Rib stabilizer, which working surface are provided with carbide insert compound and overlay, etc. The body is made from high strength alloy steel of heat treated.

3. Non-Rotaing Stabibizer: Non-rotaing stabibizer(rubber sleeve stabilizer) is a special tool to prevent the wall of casing and well, tool joint from being worn in driling procedure.

4. Replaceable Sleeve Stabilizer: Through changing sleeve to suit for different borehole diameters to lengthen operating life.

5. Tapered Stabilizer: It is suited for formation which easily reduces diameter. When happen bit freezing accident, it can leave enough operating space for fishing job.

6. Roller Reamer: It applies to all kinds of reaming jobs and is used as a stabilizer in the abrasive formation. According to the different hardnesses of formations, you may separately select sharp-fanged roller, wide-fanged roller or tungsten carbide
Compacts roller.

7. Float Valve Stabilizer: Not only as a stabilizer but also can play anti-clongging valve role in controlling downhole liquid flowing.

8. Spherical Stabilizer: It is an important tool to control hole deviation when drilling a horizontal well or a deflecting well. The stabilizer can prevent from stucking in drilling and improve the quality of well and speed of drilling, which decrease the cost of drilling.
