Structural stabilizer for fiber and conventional proppant complex in efficient proppant migration and placement technology of fractured well and preparation method

A structural stabilizer for a fiber and proppant complex to enhance proppant migration and placement in a fractured well during propping, consisting of the following components in a mass ratio:

• 84.0%-95.0% of water, 0.1%-2.0% of an inorganic salt, 0.1%-5.0% of kaolinite, 0.1%-5.0% of a nitrogen-doped modified graphene oxide, 0.1%-2.0% of an anionic surfactant, 0.1%-2.0% of a non-ionic alkyl polyglucoside, and 0.05%-0.2% of polyacrylamide;
• wherein the non-ionic alkyl polyglucoside is selected from the group consisting of C08-C14 alkyl polyglycoside, C12-C14 alkyl polyglycoside, C12-C10 alkyl polyglycoside, and combinations thereof, and wherein addition of the structural stabilizer to the fiber and proppant complex reduces a fiber escape rate and improves a proppant placement height in the fractured well.
