Product Details

API Straight/Spiral Drill String and Near-bit Stabilizer in Oil and Gas/API 7-1 Drill Stabiliser Steel and Non-magnetic

Product Description

1. Details:

Integral Spiral Blade Stabilizer is made from AISI 4145H modified alloy steel, and completely meets the requirement of API Spec 7-1 standard. It is mainly used to stabilize the drilling tools in the process of drilling hole. It also can be separated into Drill String and Near-bit types. During the production process of Drilling tool stabilizer, traceability is maintained from the receipt of raw material to completion of final products, and serial numbers are die-stamped on each work piece body. During each manufacturing process, inspection and test are performed to make sure that every piece is quality.

Features & Benefits

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

4). Tapered Stabilizer( Variable diameter stabilizer): It is suited for formation which easily reduces diameter. When happen bit freezing accident, it can leave enough operating space for fishing work.
