With the continuous growth of global energy demand, shale oil, as a significant unconventional oil and gas resource, has attracted widespread attention. The evaluation of shale oil mobility plays a crucial role in its development, directly impacting the economic viability and development efficiency of the resource. This paper explores the latest research progress on shale oil mobility evaluation, focusing on various aspects from geological characteristics to integrated assessment methods. Firstly, it introduces the geological characteristics of shale oil reservoirs, including porosity, permeability, rock mechanical properties, and organic matter content. Then, it analyzes the physicochemical properties of shale oil fluids and their flow behavior in nanopores. Next, it discusses advanced mobility evaluation methods in detail, such as Nuclear Magnetic Resonance technology, X-ray Computed Tomography technology, microfluidics, and numerical simulations coupled with Computational Fluid Dynamics. Finally, the paper looks ahead to future research directions, highlighting the necessity of conducting innovative research in interdisciplinary fields to further improve the accuracy and efficiency of shale oil mobility evaluation. This paper aims to provide a valuable reference for scientific research and technological applications in shale oil development.
