Centralizers
1. Product Overview
Introducing the Spiral Composite Rigid Centralizer, a masterpiece from STARSE Energy and Technology (Group) Co., Ltd., engineered for precision in well completion, cementing, and other critical operations. This advanced centralizer series offers unparalleled centering support for downhole tubing, ensuring an even annular clearance within the wellbore. By doing so, it significantly enhances cementing quality and operational safety. The centralizer lineup features a range of options, including spiral rigid centralizers, roller centralizers, blade centralizers, among others. Each can be meticulously chosen based on specific well conditions, tubing types, and precise process requirements.
2. Core advantages
- Our centralizers boast a diversified design, perfectly tailored for challenging environments such as vertical wells, horizontal wells, and high-angle wells;
- Constructed from high-strength materials like alloy steel and composite materials, they promise exceptional wear and corrosion resistance;
- Their streamlined structure minimizes friction, facilitating smoother pipe string entry;
- We offer bespoke sizes and surface treatments, including chrome plating and wear-resistant layers, to enhance performance.
3. Product type and structural features
Spiral Rigid Centralizer
Structure:
Crafted with an integral spiral strip design, its spiral angle is optimized through fluid mechanics, with optional wear-resistant convex points on its surface.
Features:
The spiral flow channel expertly reduces mud flow resistance and mitigates eddy current risks;
With high rigidity support, it's ideal for high-speed and high-torque situations;
Available in optional welding or detachable types, allowing for effortless onsite installation.
Roller Centralizer
Structure:
Engineered with multiple groups of freely rotating rollers, either radially or axially laid out, and each roller surface is meticulously hardened.
Features:
The rolling friction significantly diminishes pipe string resistance, ideal for extensive horizontal sections or large-displacement wells;
Rollers adapt seamlessly to the well wall's irregularities, safeguarding the casing from scratches;
Specially designed to endure high temperatures, making it perfect for deep and ultra-deep wells.
Blade Centralizer
Features 3 to 6 arc-shaped blades uniformly distributed around the circumference, with blade ends crafted with smooth chamfers.
Features:
Its lightweight structure is ideal for standard vertical wells or small wellbore operations;
The elastic blade deformation compensates for changes in well diameter, ensuring a stable centralizing force;
It's a cost-effective solution, easy to maintain, and can be deployed in batches at critical pipe string nodes.
