Examples
Embodiment 1
[0030] 1) Use quartz sand (river sand) 1000g as raw material, after scrubbing and drying, the sand does not contain water completely, and screens 20-40 mesh quartz sand as aggregate (the pretreatment process of quartz sand is the same in the following examples);
[0031] 2) Epoxy resin E-55, mixed with ethyl acetate at a ratio of 1:1. Stir evenly to prepare 50 mL of adhesive solution, then add aggregate and 10 g of guar gum to the adhesive solution.
[0032] 3) After the mixture obtained in step 2) is dried naturally, it is sieved.
[0033] The obtained proppant is particles with a particle size of 20-40 mesh (slightly larger than the particle size of the aggregate), and the surface of the aggregate is coated or partially coated with guar gum polymer material.
Embodiment 2
[0035] 1) Take 40-70 mesh 1kg quartz sand (eolian sand) as aggregate and set aside;
[0036] 2) Epoxy resin E-51, mixed with ethyl formate at a ratio of 1:1. Stir evenly to prepare 50 mL of adhesive solution, then add aggregate and 10 g carboxymethyl guar gum to the adhesive solution.
[0037] 3) After the mixture obtained in step 2) is dried naturally, it is sieved.
Embodiment 3
[0039] 1) Take 30-50 mesh 1kg quartz sand (sea sand) and sintered alumina as aggregates, the two materials have the same mesh, mix them in equal volumes, and set aside;
[0040] 2) Add 20 g of ethanol to 8 g of resole phenolic resin. Stir evenly, then add aggregate and 10g polyacrylamide to the adhesive solution.
[0041] 3) After the mixture obtained in step 2) is dried naturally, it is sieved.
