Embodiment 1
[0034] This embodiment discloses a method for preparing a low-friction composite nano-proppant, which includes the following steps:
[0035] (1) taking styrene derivatives and / or acrylic acid derivatives, and divinylbenzene as comonomers, adding modified nano-fillers, and forming high-molecular polymers through suspension polymerization to obtain composite nano-aggregates;
[0036] Styrene derivatives include one or more of styrene, methylstyrene, ethylstyrene, and dimethylstyrene;
[0037] Acrylic acid derivatives include methyl acrylate, ethyl acrylate, butyl acrylate, hexyl acrylate, octadecyl acrylate, methyl methacrylate, ethyl methacrylate, butyl methacrylate, hexyl methacrylate, methyl One or more of octadecyl acrylate, methoxypolyethylene glycol methacrylate, methacrylic acid, and allyl methacrylate;
[0038] Modified nanofillers include surfactants, silane coupling agents, titanate coupling agents, cellulose modification, glass fiber, silicon titanium iron aluminum c...
Embodiment 2
[0050] The difference between Example 2 and Example 1 is that in step (4), the polyacrylamide is anionic polyacrylamide with a content of 0.2%; the drag reducer content is 1%, and the surfactant content is 0.5%.
Embodiment 3
[0052] The difference between embodiment 3 and embodiment 1 is: in step (4), polyacrylamide is selected anionic polyacrylamide for use, and its content is 0.1%; Drag reducer content is 0.8%; Surfactant is selected benzyl chloride for use, and its content 0.08%.
