Sleeve stabilizer is a commonly used downhole tool in oil drilling operations, mainly used to stabilize the drill string, control wellbore inclination, reduce wellbore contact wear, and improve drilling efficiency. It is usually installed on drilling components such as drill rods or weighted drill rods to provide radial support and prevent the drill string from swinging or shifting in the wellbore.
1.Main functions and advantages
l Stable drill string: Keep the drilling tool in the center of the wellbore to reduce lateral swing.
l Control well deviation: Used in directional or vertical well construction to control and correct well deviation.
l Reducing wellbore wear: Reduce the frequency of contact between drilling tools and wellbore walls, and extend the lifespan of wellbore walls.
l Improving drilling efficiency: By reducing drill string vibration and friction, drilling speed and tool life can be increased.
l Simple structure and easy installation: usually designed as a sliding sleeve for quick on-site replacement.
2.Usage
l Installation location:
Generally installed between drill collars and weighted drill rods;
The specific installation location will be adjusted according to the well depth, wellbore size, and drilling objectives.
l Installation steps (overview):
Clean and inspect the outer diameter of the drilling tools;
Place the sleeve stabilizer in the designated position;
Locking/fixing (some designs are rotatable or non-rotatable
Check the centralization effect to ensure good coordination.
3.Matters needing attention:
Choose the appropriate size to match the wellbore size;
Check for wear and regularly replace;
Select materials (such as embedded alloys, hard teeth, etc.) to match drilling conditions.
