The invention discloses an airbag shell inflation suspension proppant which structurally comprises a proppant body serving as a core, the surface of the proppant body is wrapped with an inner coating, and the surface of the inner coating is wrapped with an outer coating. The inner coating comprises an adhesive and a gas generating agent, and the gas generating agent is at least two of ammonium chloride, sodium nitrite, potassium nitrite, urea, sodium carbonate, ammonium carbamate, sodium bicarbonate, ammonium nitrate, potassium nitrate, sodium nitrate, acetylsalicylic acid, citric acid, sulfamic acid and oxalic acid. The outer coating comprises a capsule shell agent, and the capsule shell agent is formed by polymerizing at least two monomers of polyethylene glycol diacrylate, polyethylene glycol dimethacrylate, tert-butyl acrylate, butyl methacrylate and styrene. Under the stimulation of a certain external environment, the gas generating agent responds and decomposes to generate gas, the outer coating wraps and seals the generated gas to form an airbag, and self-suspension of the proppant in slick water is achieved under the buoyancy effect of the airbag.
