A suspended sand dragging fiber and a preparation method thereof, the method including: dispersing nanoparticles into a first solvent, adding a coating agent and a flexibilizer to the first solvent, and stirring and aging to obtain a surface treatment agent; adding a surfactant to a second solvent, adding alkyl polyether siloxane to the second solvent after the surfactant is dissolved in the second solvent, and stirring to obtain a finishing agent; transferring the surface treatment agent to a sizing trough of a sizing machine, sizing polyester fibers using the sizing machine, and drying and curing to obtain surface-modified fibers, and diluting the finishing agent to obtain a finishing agent solution, and treating the surface-modified fibers with the finishing agent solution to obtain the suspended sand dragging fiber.

Suspended sand dragging fibers and preparation methods thereof

A structural stabilizer for a fiber and proppant complex to enhance proppant migration and placement in a fractured well during propping and a preparation method thereof are provided. The structural stabilizer consists of: water, inorganic salt, kaolinite, nitrogen-doped modified graphene oxide, anionic surfactant, non-ionic alkyl polyglucoside, and polyacrylamide. The structural stabilizer improves bonding between a proppant and a fiber when slick water is used in stimulated reservoir volume (SRV) fracturing, prevents separation of the fiber and the proppant during migration, thereby reducing escape rate of the fiber from the fiber and proppant complex.
