Series Composite Bridge Plug

The Series Composite Bridge Plug is a critical downhole tool specifically developed to isolate specific sections of wellbores, enabling targeted operations such as high-pressure stimulation, frac treatments, and cementing processes. Unlike traditional metallic bridge plugs, our composite design offers unparalleled advantages in drillability, weight reduction, and casing protection, while maintaining exceptional strength and sealing reliability under extreme downhole conditions.

Crafted with high-grade composite materials (with cast iron only used in the slip assembly), this series provides a temporary yet robust barrier that can be quickly and efficiently milled out after use, minimizing operational downtime and reducing overall project costs. With multiple configurations and versatile setting methods, it adapts seamlessly to diverse well conditions and operational requirements.

1.Advanced Composite Material Construction : The plug body is fully made of high-strength, environmentally friendly composite materials, ensuring excellent pressure and temperature resistance while enabling fast drill-out (10-20 minutes max) without damaging the casing. The unique LUG design prevents the plug from rotating with the mill shoe during drilling, further enhancing operational efficiency.

2.Versatile Configurations : Available in three main configurations to meet different operational needs:

- Standard Bridge Plug : Replaceable plug assembly for balanced pressure isolation (supports both positive and negative pressure).

- Ball Drop Bridge Plug : Basic configuration that achieves positive differential pressure sealing by dropping a ball from the surface after anchoring.

- Cage-Type Bridge Plug : Replaceable cage assembly for positive differential pressure sealing after anchoring, suitable for complex well conditions.

3.Multiple Setting Methods : Flexible setting options to adapt to different well setups, including wireline setting (compatible with BAKER 10/BAKER 20 wireline setting tools) and tubing/coiled tubing hydraulic setting (via surface pump pressure). The universal setting sleeve and shear sub allow for quick plug replacement without disassembling the setting tool.

4.Superior Sealing & Anchoring : Equipped with high-performance sealing elements and cast iron slips that bite into the casing wall with minimal depth, ensuring reliable anchoring and leak-proof sealing even in P110 grade casings. The slip cone design further enhances stability and prevents rotation during mill-out.

5.Cost-Efficient & Time-Saving : Fast drill-out capability (as low as 10 minutes) reduces rig time and labor costs. The composite material is lightweight, lowering transportation and handling costs, while the reusable setting accessories further optimize operational expenses.

6.Wide Compatibility : Designed to fit 4-1/2" and 5-1/2" casings (custom sizes available) and compatible with various casing grades, making it suitable for both vertical and horizontal wells in shale gas, oil, and geothermal projects.

The Series Composite Bridge Plug is widely used in various oil and gas well operations, providing reliable zonal isolation for :

- Multi-Stage Fracturing : Ideal for isolating multiple zones during high-pressure frac operations, allowing targeted stimulation of each reservoir zone to maximize hydrocarbon recovery.

- Well Testing & Evaluation : Used to isolate specific well sections for pressure testing, fluid sampling, and reservoir evaluation, ensuring accurate data collection without cross-zone interference.

- Temporary Well Abandonment : Provides a temporary barrier for well abandonment projects, ensuring safety and environmental compliance during idle periods.

- Cementing Operations : Serves as a temporary flow barrier during primary and remedial cementing, preventing cement channeling and ensuring proper cement placement around the casing.

- Open Hole & Cased Hole Operations : Suitable for both open hole and cased hole applications, including plug-back operations above water production or lost circulation zones.
