Curable proppant as well as preparation method and application thereof

The invention provides a curable proppant as well as a preparation method and an application thereof. The curable proppant comprises a precured film coating proppant, liquid epoxy resin A, a latent curing agent, filler and a flow modifier, wherein in terms of total weight of the precured film coating proppant, the adding amount of the liquid epoxy resin A is 2%-6%, the adding amount of the latentcuring agent is 0.2%-1.8%, the adding amount of the filler is 10%-30%, and the adding amount of the flow modifier is 0.1%-1%. The curable proppant is high in storage stability and alkali resistance, and can be solidified in a strong alkaline solution, for example, the curable proppant can be solidified in a sodium hydroxide solution with mass concentration of 1.5% at the temperature of 40 DEG C orabove, and the solidification strength is higher than 5 MPa. 本发明提供一种可固化支撑剂及其制备方法和应用。所述可固化支撑剂包括：预固化覆膜支撑剂、液体状的环氧树脂A、潜伏性固化剂、填料和流动改性剂；其中，以所述预固化覆膜支撑剂的总重量计，所述液体状的环氧树脂A的加入量为2％-6％；所述潜伏性固化剂的加入量为0.2％-1.8％；所述填料的加入量为10％-30％；所述流动改性剂的加入量为0
