In particular, this study aims to investigate the effect of aluminosilicate nanoparticle in the mixture of anionic (Sulfonated Alkyl Ester) and nonionic (Fatty Ester Oleate) surfactants on the interfacial tension and wettability related to EOR processes. Various experiments were conducted such as measuring interfacial tension between oil and brine using spinning drop tensiometer, measuring contact angle between surfactant-NPs-brine solution and Buff Berea core using optical tensiometer, conducting spontaneous imbibition, and core flooding tests.

阴离子-非离子表面活性剂混合物中硅铝酸盐对提高采收率应用中润湿性和界面张力的影响

特别是，本研究旨在研究阴离子（磺化烷基酯）和非离子（脂肪酯油酸酯）表面活性剂混合物中的铝硅酸盐纳米颗粒对与 EOR 过程相关的界面张力和润湿性的影响。进行了各种实验，例如使用旋转滴张力计测量油和盐水之间的界面张力，使用光学张力计测量表面活性剂-NPs-盐水溶液与Buff Berea岩心之间的接触角，进行自发自吸和岩心驱油测试。
