Elastic Sponge Plugging Agent-5 mm

This elastic sponge is a unique, precisely graded porous mesh sealing material featuring high compressibility, deformability, high strength, shear resistance, and high-temperature resistance—properties lacking in ordinary fiber-based plugging materials. It adapts to fractures of varying widths, forming a filter mesh at fracture sites while providing skeletal support. This transforms fractures into pores, reducing permeability in fractured formations. It simultaneously traps other sealing materials, forming a three-dimensional sealing barrier layer that enhances the retention capacity of sealing materials within fractures and increases sealing success rates. As the filling material accumulates within the filter mesh, synergizing with the mesh structure, it intensifies the compactness of the filter cake, thereby enhancing formation pressure-bearing capacity. This product is commonly employed to improve formation pressure-bearing capacity and address severe loss-of-circulation or loss-of-return-type losses. As an auxiliary material, it can be added to any type of plugging slurry, embodying the next generation of plugging technology.
