Elastic Sponge Plugging Agent-10 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 absent in conventional fiber-based sealing materials. It adapts to fractures of varying widths, forming a filtration net at fracture sites while providing skeletal support. This transforms fractures into pores, reducing permeability in fractured formations. Simultaneously, it traps other sealing materials to form a three-dimensional sealing barrier layer, enhancing the retention capacity of sealing materials within fractures and increasing sealing success rates. As the filling material accumulates within the filter mesh, synergistic effects with the mesh reinforce the filter cake's density, thereby enhancing formation pressure-bearing capacity. This product is commonly used to improve formation pressure resistance, address severe losses, and mitigate non-return-type losses. As an auxiliary material, it can be added to any type of plugging slurry, embodying a new generation of plugging technology.
