## 3 Mechanism of Molecular Deposition Film Technology
### Mechanism of Molecular Deposition Film Technology
However, it can be inferred that after the ordered growth of the MD film, the microstructure modifies the surface and alters its microstructure, various force components, and their distribution on the surface, thereby reducing adhesion. Surface properties, particularly surface adhesion, play a critical role in interfacial friction. The adsorption of the MD film reduces surface adhesion, which is an important factor in reducing friction. Deposition of the MD film agent on natural subsurface quartzite exhibits favorable friction properties crucial for enhancing oil recovery. The molecular deposition film oil displacer is instrumental in modifying the properties of solid-liquid interfaces, particularly in systems where oil and water coexist. By altering the strong oil-wetting characteristics of these surfaces, it converts them into non-wetting or weakly water-wetting states. This transformation is significant as it enhances the mobility of adsorbed oil molecules that are typically confined within a firmly adhered layer on the solid-liquid interface. As this transition occurs, the previously thick and viscous oil film adhering to the surface begins to disintegrate. The molecular interactions involved facilitate a more efficient detachment process, allowing improved flow and movement of these trapped oils away from their original positions. Consequently, this leads to a notable conversion where an extremely thick oil film is transformed into an exceedingly thin water film. This phenomenon not only optimizes fluid dynamics but also has implications for various industrial applications such as enhanced oil recovery processes, where maximizing hydrocarbon extraction efficiency is paramount. Furthermore, understanding how molecular deposition influences wettability can inform strategies in fields such as materials science and environmental engineering by providing insights into surface modifications aimed at optimizing liquid behavior across different substrates. In summary, through its capacity to modify wettability characteristics at solid-liquid boundaries, the molecular deposition film oil displacer facilitates enhanced flow dynamics by enabling trapped oils to escape from tightly bound layers while simultaneously converting those layers into thinner films predominantly composed of water rather than viscous hydrocarbons. Changing the flow properties of oil and water in reservoir pores  
The molecular deposition film oil displacement agent is instrumental in enhancing the efficiency of oil recovery processes by significantly increasing the number of capillaries within reservoir rocks. This augmentation of capillary structures is critical as it reduces the flow rate of water in macropores, thereby facilitating improved interactions between the

During the spontaneous capillary imbibition process, particularly in low-permeability oil layers that exhibit hydrophilic properties, injected water can effectively penetrate minute capillaries due to capillary action. This phenomenon results in spontaneous imbibition--a process wherein water naturally infiltrates rock formations--thereby fostering enhanced rates of oil recovery. The capacity for water to permeate these small pores is essential for displacing trapped hydrocarbons and maximizing extraction efficiency. In addition to its effects on fluid dynamics, during the MD film flooding process, when reservoir rocks interact with the molecular deposition film agent, a notable shift occurs in surface wettability towards hydrophilic characteristics. This alteration manifests to varying degrees depending on specific interactions between the agent and rock surfaces. Such changes are significant because they influence fluid behavior within porous media; increased wettability can lead to more effective mobilization of residual oils that would otherwise remain entrapped.
