“…Zhang et al [24] proposed that Darcyʹs law can be used to describe two-phase fluid flow in porous media at the macroscopic scale. Saleem et al [25] compared and verified the constructed two-phase flow model with field observation data, such as CO2 eruption time, changes in sediment pH, gas leakage rate, the flow process, fluid interaction, and CO2 dissolution in the CO2 plume. The results showed that the CO2 plume was formed and developed at a stable rate during the flow process, and the dissolution rate increased with an increase in the injection rate.…”

To prevent CO2 leakage and ensure the safety of long-term CO2 storage, it is essential to investigate the flow mechanism of CO2 in complex pore structures at the pore scale. This study focuses on reviewing the experimental, theoretical, and numerical simulation studies on the microscopic flow of CO2 in complex pore structures during the last decade. For example, advanced imaging techniques, such as X-ray computed tomography (CT) and nuclear magnetic resonance (NMR), are used to reconstruct the complex pore structures of rocks. Mathematical methods, such as Darcy's law, Young–Laplace’s law, and the Navier-Stokes equation, are used to describe the microscopic flow of CO2. Numerical methods, such as the lattice Boltzmann method (LBM) and pore network (PN) model, are used for numerical simulation. The application of these experimental and theoretical models and numerical simulation studies is discussed, considering the effect of complex pore structures. Finally, future research is suggested to focus on: (1) Conducting real-time CT scanning experiments of CO2 displacement combined with the developed real-time CT scanning clamping device to realize real-time visualization and provide quantitative description of the flow behavior of CO2 in complex pore structures; (2) The effect of pore structures change on the CO2 flow mechanism caused by the chemical reaction between CO2 and the pore surface, the flow theory of CO2 considering wettability and damage theory in a complex pore structures; (3) The flow mechanism of multi-phase CO2 in complex pore structures; (4) The flow mechanism of CO2 in the pore structures at multiscale and the scale upgrade from microscopic to mesoscopic to macroscopic. Generally, this study focuses on reviewing the research progress of CO2 flow mechanisms in complex pore structures at the pore scale and affords an overview of potential advanced developments to enhance the current understanding of CO2 microscopic flow mechanisms.

“…Erik uses the method of analog gas well leakage to study the leakage path and leakage mechanism under the worst-case scenario of CO 2 geological storage (Erik et al, 2017). Mark L et al studied the interception and accumulation effects of heterogeneous caprocks on CO 2 gas through laboratory experiments and numerical simulations (Mark et al, 2014;Ha et al, 2017;Saleem et al, 2021). Taking a natural CO 2 gas reservoir leaking site in South Africa as an object, Johnson used an analogy method to study the leakage of CO 2 geological storage along wells and faults (Johnson et al, 2017).…”

As a bottom technology for CO2 reduction, geological CO2 storage has attracted great attention from geologists, but there are few reports on the research of the caprock self-sealing effect due to CO2 leakage. Ping’an is a natural CO2 leakage site, which can be compared to the leakage scenarios of geological CO2 storage. Based on the water quality test results and geological observation data, the numerical simulation of geochemistry is carried out. The results show that: First, gypsum dissolves and calcite precipitates during the migration of CO2-rich water to the surface. This process presents a self-sealing effect, and the closer to the surface, the more obvious the self-sealing; Second, the self-sealing effect is formed rapidly. For a 30 cm wide fissure, it only takes a few hundred days to achieve self-sealing; Third, the CO2 leakage was estimated, about 140,813.3 m3, or about 251.28 tons for 1 m long fissure.
