Abstract: In light of the prevalent issue of fine particle migration during the development of unconsolidated sandstone reservoirs, the research progress and development directions were systematically elaborated. Regarding research methods for fine particle migration, experimental physical simulation and numerical simulation methods were mainly developed. Experimental physical simulation is direct and realistic, facilitating studies at both micro and macro scales. Numerical simulation offers low cost and flexible parameter control, enabling quantitative analysis and prediction of various mechanisms and dynamic changes during fine particle migration. Concerning the mechanism of fine particle migration, the classic Derjaguin-Landau-Verwey-Overbeek (DLVO) theory and hydrodynamic explanations were established, allowing for qualitatively or semi-quantitatively describe the detachment and migration of fine particles. On this basis, fluid velocity, viscosity, salinity, temperature, and pH value were identified as the key factors inducing fine particle detachment and migration. Drawing on the above mechanistic understanding, a control strategy was proposed, including optimizing the compatibility of injected fluids, controlling production pressure difference, and integrating chemical inhibition methods. Currently, the research field of fine particle migration has expanded from traditional waterflooding reservoirs to complex scenarios such as tight reservoirs, shale oil reservoirs, as well as polymer flooding, heavy oil thermal recovery, natural gas hydrate exploitation, and gas storage reservoir construction, etc. In the future, it is necessary to further deepen the research on high-precision characterization technologies and numerical simulation in aspects such as the establishment of multi-physics field coupling models and the integration of digital intelligence with interdisciplinary applications, so as to provide accurate prediction and optimized decision support for the development of complex reservoirs.
