Nano-SiO2/Polymer Composite Gel Fluid-Loss Reducer for High-Temperature, Salt-Resistant Water-Based Drilling Fluids: Performance and Mechanism
Polymeric gel fluid-loss reducers for water-based drilling fluids often undergo performance deterioration under combined high-temperature and high-salinity conditions. In this study, an organic–inorganic nanocomposite gel fluid-loss reducer, SiO2@P-DAS, was synthesized through aqueous free-radical polymerization using...
