“…For NPs, whose surface electrical properties are opposite to those of the surfactant, the wettability of the NPs will be changed by adsorption of surfactant monomers onto the NP surface so that the NPs can adsorb at the gas–liquid interface to reinforce the film strength. NPs will tend not to adsorb the like-charged surfactant by electrostatic force, and they mainly prevent the rupture of the liquid films by forming “cork” structures of NP aggregates . These aggregates are produced when NPs cross several node intersections because collisions between NPs gradually grow and are deposited faster than liquid flow …”

“…NPs will tend not to adsorb the likecharged surfactant by electrostatic force, and they mainly prevent the rupture of the liquid films by forming "cork" structures of NP aggregates. 28 These aggregates are produced when NPs cross several node intersections because collisions between NPs gradually grow and are deposited faster than liquid flow. 29 Figure 3 shows that when the concentration of nanosilica (with a negative surface charge 21 ) reaches 0.5 wt %, obvious particle aggregates are formed in the liquid films and plateau area, which can effectively inhibit liquid drainage and coalescence.…”

The blocking characteristics of two foam systems, the surfactant foam and the surfactant-nanoparticle (NP) foam, were compared. In bulk foam experiments, the drainage half-life and the foam morphological properties were tested. The pressure difference between the two ends of sandstone cores during foam flooding and subsequent water flooding was recorded to calculate the resistance factor and the residual resistance factor. An online nuclear magnetic resonance device was used to test the T 2 spectrum of the cores during the displacement experiment. The water saturation in the cores and the degree of blocking of different sizes of pores were measured. The results showed that aggregated structures of NPs between the liquid films effectively inhibited drainage and coarsening. The magnitude of the resistance factor of the foam in the core decreased as the permeability magnitude decreased. The resistance factor and the residual resistance factor of the foam with NPs were higher than those of the surfactant foam. As the permeability decreased, the reinforce effect of NPs worsened. In high/medium-permeability cores, NPs could enhance the foam-displacement effect and reduce the core water saturation after foam injection. After subsequent water flooding, the range of the T 2 spectrum of the core flooded by NP-stabilized foam was smaller, indicating that the NP-stabilized foam had a larger blocking range of pores. However, in low-permeability cores, the displacement and water-plugging effects of the two systems were similar. Increasing the concentration of NPs could further reduce the water saturation of cores with high permeability, but for low-permeability cores (23.4 mD), when the concentration of NPs increased to 0.4 wt %, the displacement effect decreased because of the clogging effect and agglomeration of NPs.

Despite rapid advances in renewable energy extraction and utilization, global oil demand continues to rise. Oil displacement technologies are widely studied and applied because they can extract more oil in depleted reservoirs or recover unconventional ones. This study introduces research methods and mechanisms of four oil displacement technologies, i.e., water flooding, chemical flooding, gas flooding, and steam flooding. Although oil displacement technologies are helping to meet the growing demand for oil and energy, there are still some challenges for industrial applications. Some agents adopted in the oil displacement have shortcomings in the corrosion of mining equipment and damage to the reservoir structure. Therefore, solutions to the problem are crucial and are investigated widely in the literature using experiments and simulations. For experimental research, a diffusion framework for studying mass transfer in the oil displacement process and an experimental system for simulating oil displacement in offshore reservoirs should be built, which will facilitate the widespread industrial application of oil displacement technology. Therefore, it is necessary to improve the accuracy and expand the application range of the experimental system. As for numerical simulation, reaction kinetics research is essential for selecting displacement agent materials and preventing harmful gas leakage for industrial applications. However, the dynamics of foam flooding and CO2 flooding are not thoroughly studied. Moreover, it is an acceptable research topic that reducing the uncertainty of discrete regions is an effective method to improve the accuracy of numerical simulation results. For the broader application of oil displacement technology to industry, several mechanisms regarding the research field could be studied more thoroughly and comprehensively in the future, i.e., (1) the influence mechanisms of some impurities and complex reservoir physical properties, (2) the method of combining various oil displacement technologies, (3) the T-H-M-C multifield coupling oil displacement mechanism at micro/nanoscale, (4) the cement failure mechanism caused by CO2 and H2S, and (5) the tube brittle fracture mechanism caused by stress corrosion. For the sustainable development and efficient utilization of oil displacement, this review summarizes the extensive information about four oil displacement technologies, thus encouraging and providing research topics for further development and applications.
