Elastic Sponge Plugging Agent-20 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 plugging materials. It adapts to fractures of varying openings, forming a filter screen at fracture sites while providing skeletal support. This transforms fractures into pores, reducing permeability in fractured formations. It simultaneously traps other plugging materials, forming a three-dimensional sealing barrier that enhances retention within fractures and increases plugging success rates. Continuous accumulation of fill material within the filter mesh, combined with its synergistic action, intensifies filter cake compaction, thereby boosting formation pressure-bearing capacity. This product is commonly used to enhance formation pressure-bearing capacity and address severe loss or non-return leakage scenarios. As an auxiliary material, it can be added to any type of plugging slurry, representing a new generation of plugging technology.
