“…Heavy oil is widely distributed in the world and plays an important role in petroleum exploration and development. , According to previous research, water flooding is difficult to effectively develop with heavy oil with high viscosity. The development technology of heavy oil has still been dominated by steam and thermal exploitation. − Thus, an efficient and convenient way to reduce the viscosity of heavy oil has become an inevitable choice for oil development. − Chemical flooding is an important method, which is aimed at improving the fluidity of heavy oil and reducing the percolation resistance in the formation. , The blockage of emulsion in the pore-throat can promote the reservoir pressure change spread to the unswept area, which is beneficial to developing the heavy oil reservoir …”

Chemical flooding is an effective method to enhance heavy oil recovery, and the viscosity reducer is often injected into the formation as the main reagent of chemical flooding. In the paper, a novel polymer viscosity reducer (FMP) was used to inject into a visual filling model, which can simulate the reservoir. The mechanism of enhancing heavy oil recovery by FMP is studied by macroscopic and microscopic analysis methods. The model can obtain macroscopic images and production data, including pressure, water cut, and oil recovery. The model can observe some microscopic processes, which can analyze the mechanism of enhanced oil recovery. Five processes of emulsifying viscosity reduction are summarized by using microscopic images: membrane oil removal, gradual emulsification, flocculation into droplet groups, active dispersion, and agglomeration into droplets. The FMP molecules can affect the interfacial properties of oil, water, and rock to enhance the wishing oil efficiency. Moreover, the decrease in the stability of the oil–water interface leads to flocculation into droplet groups and agglomeration into droplets occurring at the throat of the strong seepage zone, which increases the sweep coefficient from 0.56 to 0.90. The oil recovery has increased from 18 to 34%, which indicates that the FMP flooding obviously enhances the effect of heavy oil reservoir development.

Emulsified behaviors are of importance for chemical flooding. Properties of emulsifiers relate droplets coalescence and transport. Since experiments do not provide access to observables of interest. Numerical simulations with mesoscale scheme pose attractive method to gain insight into emulsifying stability, which is defined as a period of oil droplets movements at fixed ranges. A phase field based lattice Boltzmann model is used which simulate interface behavior. Various parameters including emulsified droplet size, interface thickness, viscosity ratio and density ratio have been discussed. The aim of this study is to provide a critical suggestion that predictive emulsifying behaviors of small oil droplets immersed in water environment.
