High-Performance Rubber Element for Downhole Completion Tools

Shaanxi Hagrien Energy Technology Co., Ltd. delivers engineered Rubber Element solutions designed for demanding wellbore environments. Our components support your completion tool systems with proven sealing reliability, thermal stability, and chemical resistance. Manufactured from precision-grade elastomeric compounds, each element undergoes strict quality control to ensure dimensional consistency and performance repeatability. With Shore hardness ranging from 60 to 90 Shore A and temperature resistance up to 200°C, our products meet the demands of multi-stage fracturing, HPHT operations, and isolation systems. Backed by ISO-certified manufacturing and CNAS-accredited testing, we provide full traceability, COA documentation, and engineering support from prototype to volume production.

What Is a Rubber Element?

A product is a precision-formed elastomeric component that creates flexible, pressure-tight seals in downhole tools. You'll find it inside bridge plugs, packers, and setting assemblies where metal alone cannot maintain fluid isolation.

It works by deforming under compression. When your tool sets downhole, the element expands radially against the casing wall. This contact creates a barrier that holds back reservoir pressure, treatment fluids, or proppant slurry.

Different well conditions demand different polymer bases. HNBR suits high-temperature gas wells. NBR handles oil-based fluids. FKM resists aggressive acids and steam. Your choice depends on temperature, chemistry, and how long the seal must hold.

Key Technical Properties You Should Evaluate

Choosing the right component means understanding how it behaves under load and exposure. Here's what matters most:

Property
Typical Range
Why It Matters
Shore Hardness
60–90 Shore A
Controls compression force and extrusion resistance
Tensile Strength
12–22 MPa
Prevents tearing during set and release
Compression Set (70h@150°C)
≤25%
Ensures the seal recovers and maintains contact
Temperature Range
-40°C to +200°C
Defines operational envelope for your well profile
Elongation at Break
≥200%
Allows conformity to irregular casing or tool surfaces
Volume Swell (in oil, 70h)
≤15%
Prevents dimensional instability in hydrocarbon exposure

These parameters are not abstract specs. They directly affect how your plug sets, how long it holds pressure, and whether it releases cleanly during mill-out.

Core Advantages of Hagrien Rubber Elements

1. Excellent Wellbore Sealing Performance

Our elements create reliable annular barriers in cased and open holes. The polymer formulation and geometry are co-designed to maximize surface contact and minimize bypass risk.

2. High Resistance to Temperature and Pressure

Tested in HTHP autoclaves, our components maintain seal integrity at pressures exceeding 10,000 psi and temperatures up to 200°C. You get predictable performance in deep, hot wells.

3. Strong Oil and Chemical Resistance

Whether you're pumping diesel, brine, or acid, our material selection ensures minimal swelling and no degradation. This keeps your toolstring dimensions stable and your isolation zone secure.

4. High Elasticity and Anti-Extrusion Capability

The rubber compound balances flexibility with mechanical strength. It compresses to seal, yet resists extrusion into gaps between metal components—a common failure mode in high-differential-pressure scenarios.

5. Suitable for a Wide Range of Downhole Operations

From temporary fracturing barriers to permanent zonal isolation, our portfolio covers multi-stage completions, cementing operations, and workover interventions.

How Rubber Elements Perform in Real Wellbore Conditions?

In multi-stage hydraulic fracturing, your plug must isolate treating pressure between stages. The product compresses against the casing as the slip system bites. It holds 8,000–10,000 psi differentials while proppant-laden slurry flows past at high velocity. After the stage, you mill through it cleanly without damaging the casing.

In HPHT gas wells, a permanent packer relies on stacked elastomer cups to prevent gas migration across zones. Here, long-term thermal aging and CO₂ exposure test the polymer's resilience. Our FKM-based formulations maintain compression force for years, even at elevated downhole temperatures.

In enhanced oil recovery, steam injection wells see temperatures near 250°C and cyclic thermal stress. EPDM or Aflas-based elements resist steam aging and maintain elasticity through repeated heating and cooling, preventing steam breakthrough that would compromise flood efficiency.

Why International Buyers Choose Hagrien?

You need more than a part number. You need a supplier who understands your toolstring design, your operational envelope, and your supply chain constraints.

Application-Oriented Engineering Support

We match polymer type, hardness, and geometry to your specific well profile. Share your temperature, pressure, fluid type, and seal duration—we'll recommend the formulation that balances cost and performance.

Integrated Supply for Plug Systems

Because we manufacture both dissolvable magnesium components and rubber elements, you can source your entire plug assembly from one supplier. This reduces coordination overhead, shortens lead times, and simplifies quality audits.

Traceability and Documentation

Each group comes with a Certificate of Examination (COA) appearing hardness, pliable quality, compression set, and dimensional assessment comes about. Full traceability from crude compound to wrapped up portion underpins your provider capability and review requirements.

Predictable Lead Times

Standard durometers and sizes transport in 2–4 weeks. Custom definitions or geometries take 4–8 weeks. We keep up security stock for high-volume profiles to buffer against request spikes.

Prototype to Volume Production

We back your improvement cycle with test clusters, execution testing in our CNAS-accredited HTHP lab, and adaptable fabricating that keeps up consistency from 100 pieces to 10,000 pieces.

Frequently Asked Questions

1. What is the product mainly used for?

The product is mainly used for wellbore sealing, pressure isolation, and packer or plug sealing systems. Buyers usually want to know whether the product can meet the target working condition, machining route, and final application requirement without creating unnecessary downstream risk.

2. What key features should buyers evaluate when sourcing the product?

Buyers should evaluate temperature resistance, chemical compatibility, compression recovery, and sealing reliability. In export purchasing, these factors matter because they directly affect processing yield, field reliability, product consistency, and the total cost of qualification.

3. Why do international buyers choose Hagrien for the product?

Hagrien supports completion-tool buyers with application-oriented sealing knowledge, product matching, and coordinated supply for plug systems and downhole assemblies. This helps customers reduce dependence on a single supplier, improve communication speed, and move from sample validation to stable volume supply more efficiently.
