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...

Ultra-High Temperature Resistant and Environmentally Friendly Polymer Water-Based Drilling Fluid: Development, Performance Evaluation, and Field Application

Global oil and gas exploration is increasingly moving towards deeper formations. However, under the complex and harsh conditions of ultra-high temperature, high pressure, and salt-gypsum layers, the performance of conventional water-based drilling fluids deteriorates significantly, leading to frequent drilling incide...

High-Temperature-Resistant Long-Term Stable Clay-Free Water-Based Drilling Fluids for Deep Well Drilling and Reservoir Protection

Under high-temperature and high-pressure conditions, drilling fluids with long-term stability and low formation damage are one of the key technologies for ensuring safe and efficient drilling in deep reservoirs and achieving higher oil and gas production. In this study, a zwitterionic polymer (SPG) with high-temperat...
