Abstract

Further studies into drilling fluids especially to reduce the use of oil and synthetic-based drilling fluids are ever-growing due to their contributions to environmental pollution. This study, therefore, attempts to evaluate the thermal, viscosity, surface tension, and filtration loss properties of water-based drilling fluids (WBDFs) upon the addition of Gemini surfactant-silica nanofluid. This surfactant-nanofluid was formed by dissolving silica nanofluid in the surfactant solution, and ultra-sonication was used to attain homogeneity. Characterization of the Gemini surfactant-silica (SiO₂) nanofluid was done by Fourier Transform Infrared Spectroscopy (FTIR). The viscosity, surface tension, and filtration loss properties were studied using the rheometer, tensiometer, and low-pressure, low-temperature (LPLT) filter press respectively. The experimental results showed that Gemini surfactants contributed to the highest increase in drilling fluid viscosity compared to a conventional surfactant. Also, when combined with silica-nanoparticles showed better thermal stability with an 11% average change in viscosity with increasing temperature and a decrease in surface tension and filtration loss both showing a 17% and 12% decrease respectively.

应用二氧化硅(SiO2)纳米流体和Gemini表面活性剂改善水基钻井液的黏性和表面张力

由于石油和合成基钻井液会造成环境污染，因此对钻井液的进一步研究，特别是减少石油和合成基钻井液的使用，正在不断发展。因此，本研究试图评估添加Gemini表面活性剂-二氧化硅纳米流体后水基钻井液(WBDFs)的热性能、粘度、表面张力和滤失性能。将二氧化硅纳米流体溶解在表面活性剂溶液中形成表面活性剂-纳米流体，并利用超声波达到均匀性。利用傅里叶变换红外光谱(FTIR)对Gemini表面活性剂-二氧化硅(SiO2)纳米流体进行了表征。分别用流变仪、张力仪和低压低温压滤机对其粘度、表面张力和滤失性能进行了研究。实验结果表明，与常规表面活性剂相比，Gemini表面活性剂对钻井液粘度的贡献最大。此外，当与二氧化硅纳米颗粒结合时，表现出更好的热稳定性，粘度随温度升高平均变化11%，表面张力和过滤损失分别下降17%和12%。

期刊介绍： Egyptian Journal of Petroleum is addressed to the fields of crude oil, natural gas, energy and related subjects. Its objective is to serve as a forum for research and development covering the following areas: • Sedimentation and petroleum exploration. • Production. • Analysis and testing. • Chemistry and technology of petroleum and natural gas. • Refining and processing. • Catalysis. • Applications and petrochemicals. It also publishes original research papers and reviews in areas relating to synthetic fuels and lubricants - pollution - corrosion - alternate sources of energy - gasification, liquefaction and geology of coal - tar sands and oil shale - biomass as a source of renewable energy. To meet with these requirements the Egyptian Journal of Petroleum welcomes manuscripts and review papers reporting on the state-of-the-art in the aforementioned topics. The Egyptian Journal of Petroleum is also willing to publish the proceedings of petroleum and energy related conferences in a single volume form.
