▎ 摘　　要

NOVELTY - Coated proppant comprises a proppant particle, an intermediate cross-linked terpolymer layer encapsulating the proppant particle, and an outer resin layer encapsulating the intermediate cross-linked terpolymer layer. USE - Coated proppant for use in fracturing operations, protecting the proppant particle from degradation by the presence of aqueous fluids at down holes temperature. ADVANTAGE - The coated proppant increases the surface area of the particle, prevents proppants that are crushed from releasing proppant fines, which may migrate into the formation and restrict flow conductivity of the formation thus break down when stress is increased, such as at pressures deep within a subsurface formation.
