Product Description

Centralizers

1. Product Overview
This series of downhole centralizers is specially designed for well completion, cementing and other operations. It can provide efficient centering support for downhole tubing, ensure uniform annular clearance of tubing in the wellbore, and improve cementing quality and operation safety. The products include spiral rigid centralizers, roller centralizers, blade centralizers, etc., which can be flexibly selected according to well conditions, tubing types and process requirements.
 

2. Core advantages

 

1. Diversified design, suitable for complex working conditions such as vertical wells, horizontal wells, and high-angle wells;
2. High-strength materials (such as alloy steel and composite materials) ensure wear resistance and corrosion resistance;
3. Optimized structure reduces friction and reduces resistance to pipe string entry;
4. Customized sizes and surface treatments (such as chrome plating and spraying wear-resistant layer) can be provided.

3. Product type and structural features

Spiral Rigid Centralizer
Structure:
The main body is an integral spiral strip design, the spiral angle is optimized by fluid mechanics, and wear-resistant convex points can be added on the surface.
Features:
The spiral flow channel reduces the flow resistance of mud and reduces the risk of eddy current;
High rigidity support, suitable for high speed and high torque conditions;
Optional welding or detachable type, easy to install on site.

Roller Centralizer

Structure:
The main body is inlaid with multiple groups of freely rotating rollers (radial or axial layout), and the roller surface is hardened.
Features:
Rolling friction significantly reduces the resistance of the pipe string, suitable for long horizontal sections or large displacement wells;
The roller can adapt to the irregular shape of the well wall to protect the casing from scratches;
High temperature resistant design, suitable for deep wells and ultra-deep wells.

Blade Centralizer

3~6 arc-shaped blades are evenly distributed around the circumference, and the blade ends are designed with smooth chamfers.
Features:
Lightweight structure, suitable for conventional vertical wells or small wellbore operations;
Elastic deformation of the blades can compensate for changes in well diameter and provide stable centralizing force;
Low cost, easy maintenance, and can be configured in batches at key nodes of the pipe string.
