Product Description

API 7-1 oil well bottom near-bit Stabilizer
 

1. Description
Stabilizer, also known as centralizer, is a tool for stabilizing downhole 
drilling tools and preventing deflection, a device connected to a section of 
drill pipe string close to the large-diameter drilling tool, to stabilize the 
drilling direction. It is also an important tool for preventing well 
deviation changes in oil, natural gas and geological exploration drilling 
projects.

 

2. Application
In the case of using a more rigid drill collar and applying a greater weight 
on bit, reasonably using the stabilizer can reduce the rate of change in well 
deviation and azimuth, avoid the occurrence of "dogleg" well patterns, and 
improve the quality of the well & drilling speed, reducing drilling costs.

 

3. Classification
Drilling tool stabilizers are divided into four types according to the 
structure:
(1) integral spiral stabilizer; the integral three-helix and four-helix 
stabilizers are divided into bottom hole type and drill string type. The 
wear-resistant material on the working surface includes 
    1) carbide insert,

    2) Inserted diamond compound,

    3) Low temperature brazing tungsten carbide slug,

    4) Surface bead welding abrasive welding rod, etc.
(2) Integral straight blade stabilizer;

(3) Roller stabilizer;

(4) replacable sleeve stabilizer.
