A seawater-based,high-temperature-resistant fracturing fluid system was constructedfrom M-NS and carboxymethyl hydroxypropyl guar gum (CMHPG). The resultsshowed that 3-aminopropyltriethoxysilane (APTES) modification improved,to a certain extent, the dispersion stability and interfacial compatibilityof nano-SiO₂ (NS) in the seawater-based CMHPG solution.The optimal formulation of the M-NS-enhanced system was 0.4 wt % CMHPG,0.5 wt % organic zirconium crosslinker, 0.08 wt % M-NS, 0.1 wt % APS,and 0.05 wt % SDS. After shearing at 200 °C and 100 s^–1 for 2 h, the retained viscosity was 60.03 mPa·s, which was1.42 times that of the conventional system. At 95 °C, no proppantsettling was observed at sand ratios of 10%, 20%, and 30%. In addition,the fracturing fluid exhibited favorable breaking and flowback performance,dynamic leak off control performance, and formation-damage performance.Investigation of the high-temperature-resistance mechanism revealedthat the M-NS-enhanced fracturing fluid system demonstrated excellentviscosity recovery and nonlinear elastic response under large strain.This improvement is attributed to the formation of physical crosslinkingthrough hydrogen bonding between the −NH₂ on theM-NS surface and the hydroxyl and carboxymethyl groups on the polymerchains. This physical crosslinking mechanism likely synergizes withthe organic zirconium chemical crosslinking to construct a dual-networkstructure. Moreover, M-NS is uniformly dispersed in the CMHPG basefluid, acting as rigid nucleation points and a skeleton. Consequently,the network skeleton of the enhanced gel is significantly thickened,and the structure of the gel is enhanced.
