High-Pressure Bridge Plug Elements with HNBR and FKM Sealing Solutions for Oil, Gas, and Gas Condensate Environments

High-Pressure Bridge Plug Elements HNBR and FKM Sealing Solutions

Product Introduction

The High-Pressure Bridge Plug Elements are critical components in downhole zonal isolation, designed to provide a secure and reliable seal in the most demanding wellbore environments. Whether used in permanent or retrievable bridge plugs, these elements are engineered to withstand extreme differential pressures and aggressive chemical exposure. By utilizing high-performance elastomers like HNBR and FKM, our sealing elements ensure a gas-tight seal that facilitates fracturing, acidizing, and well abandonment operations. These elements are precision-molded to expand uniformly under mechanical or hydraulic force, ensuring complete contact with the casing wall.

Material Properties

We specialize in two high-tier elastomer materials to ensure success in hostile downhole conditions:

HNBR Hydrogenated Nitrile Butadiene Rubber: Known for its exceptional physical strength and mechanical toughness. HNBR offers excellent resistance to abrasion, extrusion, and tearing. It is highly effective in environments containing Hydrogen Sulfide (H2S) and Carbon Dioxide (CO2) while maintaining its elasticity under high-pressure cycles.

FKM Fluorocarbon: The premier choice for extreme thermal stability. FKM is highly resistant to chemical attack from various wellbore fluids, including aromatics and aggressive acids. It is the gold standard for high-temperature and sour gas (H2S) applications where other elastomers might soften or lose sealing integrity.

Material Comparison: FKM vs HNBR

While both materials are designed for high-performance sealing, they serve different primary functions:

Mechanical Durability: HNBR is significantly tougher than FKM. It resists tearing and abrasion better, making it ideal for operations where the plug might be subjected to significant mechanical stress or high-velocity fluid movement.

Thermal Resistance: FKM can withstand much higher continuous temperatures (up to 200C) compared to HNBR (up to 160C). For ultra-deep or high-temperature reservoirs, FKM is the necessary choice.

Chemical Resistance: FKM offers a broader range of chemical compatibility, especially with aggressive completion fluids and aromatics. HNBR is excellent for H2S and CO2 but may be more susceptible to certain chemical solvents than FKM.

Low Temperature: HNBR typically maintains better flexibility in colder surface temperatures or during initial deployment compared to FKM.

Application   

Application environment: oil, gas, gas condensate

Shanghai Qinuo manufactures a wide range of Packer Cups and replacement Packer Cups for the leading Packer Cup manufactures. These Packer Cups are developed to perform in varying well conditions and provide maximum durability and sealability in the toughest of oilfield conditions.

We manufacture both Wire Skeleton / Wire Mesh / Wire Frame Packer Cups and Rubber Packer Cups without any mesh.

Our Packer Cups are available in various sizes right from a 1-1/4″ tubing through a 7″ casing and more. Specific sizes / designs can be developed based on your requirements.

Other relative rubber products:

Our products are widely used at all kinds of cars, machinery, home appliance, electronic products, electric appliance, stationery, computers, oil equipment, and hardware spare parts.

• The TA swab cup is a medium-duty, all-rubber variable lip cup that offers greater flexibility under lighter loads.
• The MV swab cup is a light-duty, all-rubber cup especially effective in fluid with a high ratio of suspended sand. It has multiple flexible, upturned lips that easily.
• The V swab cup is a ring-type, single-lip, flexible, all-rubber cup molded on a steel bushing. It is ideal for lifting sand-laden fluids and for light-load swabbing. It is a single version of the MV swab cup.
• The TUF swab cup is a flexible, synthetic rubber cup with spring steel reinforcing wires for heavy loads but is flexible enough for light or medium loads.
• The UF swab cup is an all-purpose, synthetic rubber cup containing strong, flexible spring steel reinforcing wires.
• The J swab cup is a durable, heavy-duty cup with a long, flexible lip and strong steel reinforcing wires which provide a good upstroke seal for lifting heavy loads.
• The GW swab cup is a heavy, flexible, single-lip cup reinforced by spring steel wire. The oversized lip creates a good upstroke seal.

Packing and shipping

1: Express: S.F. ,DHL,UPS, TNT, FedEx ect, for urgent and small order.

2: Air shipment: air port to air port , or air port to door.

3: Sea shipment: suitable for bulk goods. it will takes more longer time than air shipment.
