▎ 摘　　要

NOVELTY - Structure stabilizer of fiber and existing supporting agent composite, comprises water, inorganic salt, kaolin, nitrogen-doped modified graphene oxide, anion surfactant, non-ionic short chain alkyl glycoside and polyacrylamide. USE - The structure stabilizer of fiber and existing supporting agent composite is useful for high-efficiency supporting agent paving technology of fracturing wells (claimed). ADVANTAGE - The structure stabilizer of fiber and existing supporting agent composite solves the problem that current volume fracturing when using the sliding water, supporting agent is tightly combined with fiber resulting in separation of fiber and supporting agent during conveying process and high escape rate of fiber from composites. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing structure stabilizer of fiber and existing supporting agent composite, comprising (i) mixing kaolin, water and inorganic salt, stirring for 0.5-3 hours to obtain uniform slurry and (ii) continuously stirring, adding nitrogen-doped modified graphene oxide, anion surfactant non-ionic short chain alkyl glucoside and polyacrylamide, stirring for 5-30 minutes to obtain final product.
