The application of nanoparticles (NPs) in the oil and gas industry has received wide attention in recent years because it is increasingly being considered a promising approach to recovering trapped oil in conventional hydrocarbon reservoirs. Numerous studies have demonstrated that combining nanoparticles with a surfactant can enhance surfactant performance by changing the interfacial properties of the solution when it comes in contact with crude oil and rock surfaces. However, more information and additional experimental data are required concerning the application of titanium dioxide nanoparticles in alkyl ethoxy carboxylic surfactants. In this study, we measure the changes in interfacial tension and wettability due to the addition of titanium dioxide nanoparticles (0, 100, 250, and 500 ppm) in alkyl ethoxy carboxylic surfactant using a spinning drop tensiometer and contact angle measurements. The interfacial tension of the crude oil-water (surfactant) system decreases by approximately two orders of magnitude with an increasing titanium dioxide concentration, exhibiting a minimum value of 5.85 × 10 mN/m. Similarly, the contact angle decreases on the surface of the Berea sandstone by combining the surfactant with titanium dioxide, reaching a minimum contact angle of 8.8°. These results demonstrate the potential of this new approach to maximize the recovery of trapped oil and significantly improve oil production.
近年来，纳米颗粒（NPs）在石油和天然气工业中的应用受到了广泛关注，因为它越来越被认为是一种在常规碳氢化合物储层中回收被困石油的有前途的方法。大量研究表明，将纳米颗粒与表面活性剂结合可以通过改变溶液与原油和岩石表面接触时的界面性质来提高表面活性剂的性能。然而，关于二氧化钛纳米颗粒在烷基乙氧基羧酸盐表面活性剂中的应用，还需要更多信息和额外的实验数据。在本研究中，我们使用旋滴张力仪和接触角测量方法，测量了在烷基乙氧基羧酸盐表面活性剂中添加二氧化钛纳米颗粒（0、100、250和500 ppm）后界面张力和润湿性的变化。随着二氧化钛浓度的增加，原油-水（表面活性剂）体系的界面张力降低了约两个数量级，最小值为5.85×10 mN/m。同样，通过将表面活性剂与二氧化钛结合，在贝雷砂岩表面的接触角减小，最小接触角达到8.8°。这些结果证明了这种新方法在最大限度地回收被困石油和显著提高石油产量方面的潜力。
