Embodiment 1
[0038] Such as figure 1 with 2 as shown, figure 1 is a schematic diagram of the structure of a conventional proppant. figure 2 It is a structural schematic diagram of the film-covered proppant of the present invention. It can be seen that the film-coated proppant of the present invention has a core-shell structure, the core of which is a conventional proppant, and the surface of the conventional proppant is sequentially wrapped with a connecting layer and a shell layer. The connecting layer is located between the core and the shell, and is used for fixedly connecting the core and the shell.
Embodiment 2
[0040] A kind of preparation of membrane proppant:
[0041] The film-covered proppant uses quartz sand as the core, 3-aminopropyltriethoxysilane and 3-chloro-1,2-propylene oxide as the connecting layer, and cocoamidosulfobetaine as the shell layer. All raw material formulations are as shown in Table 1:
[0042] Table 1 Raw materials used in film-coated proppants
[0043]
[0044] Preparation method steps:
[0045] (1) Select 20 / 40 mesh quartz sand and add it to the reaction vessel, soak it with 1wt% HCl solution for 30 minutes to remove the stains on the surface of the quartz sand; filter the liquid, wash with water to remove residual acid until neutral; After drying for 2 hours, set aside.
[0046] (2) Take 3-aminopropyltriethoxysilane and add it to the reaction vessel, add ethanol as a solvent, and stir at room temperature for 10mim; Mix well; raise the temperature of the reactor to 80°C, and react for 3h until the solvent is completely evaporated; continue to raise t...
Embodiment 3
[0050] A preparation method of film-coated proppant:
[0051] The film-covered proppant selects 40 / 70 mesh ceramsite as the core, N-(β-aminoethyl)-γ-aminopropyltriethoxysilane and glutaraldehyde as the connecting layer, and 10,000 molecular weight oil-soluble polymer as the shell Floor. All raw material formulations are as shown in Table 2:
[0052] Table 2 Raw materials used in film-coated proppants
[0053]
[0054] Preparation method steps:
[0055] (1) Select ceramsite of 40 / 70 mesh and add it to the reaction container, soak it with 1wt% HCl solution for 30 minutes to remove the stain on the surface of the quartz sand; filter the liquid, wash it with water to remove the residual acid until neutral; After drying for 2 hours, set aside.
[0056] (2) Take N-(β-aminoethyl)-γ-aminopropyltriethoxysilane into the reaction vessel, add ethanol as a solvent, and stir at room temperature for 10mim; then add step (1) to the reaction vessel to wash Clean and dry quartz sand, st...
