Blocking Composite Bridge Plug

Our Blocking Composite Bridge Plug is a critical downhole tool engineered for efficient zonal isolation in oil and gas drilling, workover, and completion operations. Designed with advanced composite materials, it delivers reliable blocking performance to isolate specific wellbore intervals, enabling targeted fracturing, well testing, acidizing, or well abandonment tasks. Unlike traditional metal bridge plugs, our composite design combines exceptional strength, superior sealing, and easy drillability, significantly reducing operational time and costs while ensuring safety and durability in harsh downhole environments.

1.Superior Blocking & Sealing Performance : Equipped with nano-modified rubber sealing sleeves and adaptive slip structures, the plug achieves tight zonal isolation, effectively blocking fluid flow from both above and below the tool. It maintains reliable dynamic sealing under extreme conditions of up to 300°F (150°C) and 10,000 psi (70 MPa), preventing cross-zone contamination and ensuring operational safety.

2.High-Efficiency Drillability : Made of 97% premium composite materials (glass fiber-reinforced epoxy resin or carbon fiber-epoxy matrix), the plug can be easily milled with conventional or coiled tubing tools. Milling time is reduced by up to 50%, producing small, lightweight cuttings that can be quickly circulated out of the wellbore without causing stuck pipe issues.

3.Fast & Safe Running-In : The smooth mold-made sealing sleeve and optimized structural design allow a running speed of up to 500 ft/min, minimizing the risk of expansion, jamming, or premature setting. The plug can be set via wireline (compatible with Baker E-4/E-5 assemblies) or coiled tubing, adapting to different operational requirements with high flexibility.

4.Durable & Corrosion-Resistant : The composite material boasts excellent high-temperature and high-pressure resistance, as well as strong corrosion resistance against downhole fluids (oil, gas, water). It avoids the wear, rotation, and damage issues common with brittle metal components, ensuring long-term reliability in diverse well conditions (vertical, deviated, and horizontal wells).

5.Cost-Saving Operation : By reducing running-in time, milling time, and the need for multiple trips, our Blocking Composite Bridge Plug lowers overall rig costs and operational expenses. Its lightweight design also reduces transportation and handling costs, delivering greater economic benefits for your oilfield projects.

- Running-In : The plug is delivered to the target wellbore interval via wireline or coiled tubing, with the guide shoe ensuring smooth movement and preventing jamming.

- Setting : Hydraulic or mechanical force is applied to activate the setting tool, which pushes the cones to expand the slips. The slips anchor firmly to the casing wall, while the sealing sleeve expands to form a tight seal between the plug and the casing, achieving zonal isolation.

- Blocking & Operation : The solid bore design of the plug completely blocks fluid flow, allowing targeted operations (fracturing, testing, etc.) on the isolated interval.

- Milling & Removal : After completion of operations, the composite plug can be quickly milled using conventional drilling tools or coiled tubing-deployed motors. The milled cuttings are lightweight and easy to circulate out, enabling "one-trip milling" and improving operational efficiency.

Our Blocking Composite Bridge Plug is widely used in various oil and gas operations, especially suitable for :

- Multi-stage fracturing operations in shale gas and unconventional oil reservoirs

- Zonal isolation for well testing, acidizing, and stimulation treatments

- Temporary or permanent well abandonment

- Vertical, deviated, and horizontal well operations

- Underbalanced drilling and completion operations

- Squeeze cementing and formation plugging tasks
