Chemical flooding has become an important method to enhance oil recovery in high‐water cut reservoirs. Crude oil emulsification often occurs during chemical flooding, and it plays a very positive role in increasing crude oil production. Crude oil emulsification increases the complexity of fluid flow in the reservoir including multifield coupling characteristics and multiphase flow and multiphase form characteristics. This paper discusses advanced research techniques and the status of multiphase fluid flows in chemical flooding, including the interfacial rheological properties of emulsions, physical simulation of emulsion seepage, and mathematical models and numerical simulations of seepage. Studies on the mechanism of seepage have analyzed the macroscopic and microscopic aspects of seepage during chemical flooding. Prospective directions for future research are indicated including the study of the interfacial rheological characteristics of emulsions, methods for the evaluation of the seepage characteristics of chemical flooding, and mathematical models of multiphase seepage during chemical flooding.

“…The finite volume method is used to study the oil and water two-phase flow at pore scale because of its good conservation and applicability for complex geometry [6], mainly including volume of fluid (VOF) methods [20][21][22][23], level set methods [24], and phase field (PF) method [25,26]. Iyi et al used a volume of fluid model to simulate the transport process of oil and water two phases in pore channels and considered the effects of temperature, contact angle, and surface tension.…”

The study on the flow behaviors of oil and water two phases in porous media and their influencing factor is very important to adjust the porous carbonate reservoir development strategy and enhance the oil recovery. Based on the CT (computed tomography) scanning of real carbonate reservoir core sample, the micropore structure was reconstructed, and the effects of different factors (injection rate, oil-to-water viscosity ratio, and contact angle) and secondary development methods (higher injection rate and water displacement direction optimization) on the flow behavior of oil and water two phases were explored by numerical simulation in this paper. It is found from the study that the pores in the porous carbonate reservoirs have good structural connectivity. During the displacement process, the oil-water interface mainly resides at the pore throat junction with a large change of pore size, and the Haines jumps exist in the oil-water movement; the areal sweep efficiency of the water phase is jointly affected by the viscosity effect, interfacial tension, pore structure, and injection rate. Under the minimum injection rate and oil-to-water viscosity ratio, the maximum oil recovery can be obtained, and the oil recovery is 52.62% and 57.01%, respectively. The recovery efficiency and swept area are better in a water-wet system than oil-wet system. During the secondary development, the remaining oil is hardly displaced even with the injection rate increased by a factor of 50, and it shows improvement after 250 times of initial injection rate. Changing the position of water inlet and the produced fluid outlet results in better recovery since the remaining oil near the new inlet and outlet can be effectively produced.

“…Nowadays, several approaches have been developed for the issues of multiphase flow, including the CT experiment [7,8], the pore network model [9], the lattice Boltzmann method (LBM) [10], the level set method [11], the volume-of-fluid (VOF) method [12], as well as the phase field method [13][14][15]. The research based on these methods for fracture modeling has been greatly developed.…”

Due to the complex conditions of carbonate reservoir, in this paper, a unified lattice Boltzmann method was used to study the rule of the flow in carbonate reservoir as the foundation. Two group models were designed to simulate the influences of fractures and vugs. In experiments, at first, the model for carbonate reservoir considering different amounts and lengths of fractures was considered. Then, the model was improved by taking the influences of fractures and vugs into consideration. The result from the first group shows that the whole permeability enhanced a lot when multiple fractures form a big one which connects to two boundaries. At the same time, the main result of the other group shows that the main capability of vugs is flow accumulation. Through a series of experiments, the flow rule in carbonate reservoir with vugs and fractures is proved based on LBM theory, which has a huge impact on the study in LBM and researches on carbonate reservoir.
