In geothermal drilling, the significant rheological deterioration of biopolymer drilling fluids can lead to decreased cutting-carrying efficiency and fluctuations in annulus pressure, which easily result unpredictable downhole accidents. To address challenges, this study innovatively introduces temperature-sensitive monomers (NIPAM) nanosilica into molecular chains based on temperature response effects adsorption stability counteract negative salt ions, aiming develop a agent (PNA-SiO2) that is resistant high salt. The structure thermal PNA-SiO2 were characterized by FT-IR TGA, it was demonstrated have main chain within 317 °C. According filtration studies, effectively addresses issues high-temperature viscosity attenuation sharp rise volume bentonite mud aggressively adsorbing, creating stable thixotropic network, enhancing repulsion. After aging at 60-180 °C, fluid with 2-4% has excellent rheology (AV ≥ 57.5 mPa·s, PV 42 Gel10 min 1.533 Pa) (FLAPI ≤ 9.6 mL) properties fully satisfy API requirements. H-B model preferred accurately describe behavior fluids. Moreover, under comprehensive influence Na+ interlayer spacing thickness diffusion bilayer, applicability saturated saline water. 150 °C 5-36% NaCl, exhibits 55 44 mPa·s) low (≤9.6 mL). conclusion, used as loss agent, offering cost-effective solution technical severe leakage inadequate capacity encountered enables safe quick exploration resources.
