| 英文摘要 | Mineral dissolution exists in numerous subsurface environments and energy engineering applications. Unlike the dissolution of pure substances, in realistic scenarios, this process is influenced by the type and distribution of minerals, thereby changing the local dissolution rate. On the contrary, local dissolution disparity gives rise to flow and solute transport heterogeneity. Such heterogeneity significantly influences processes like diagenesis, unconventional oil and gas reservoir development, and carbon storage. However, the quantification of mineral dissolution disparity in relation to flow and transport heterogeneity is relatively understudied. Numerical simulators are powerful tools for investigating reactive transport. Common approaches include continuum-scale simulations and pore-scale simulations. However, continuum-scale simulations often overlook the heterogeneity within the pore scale, whereas pore-scale simulations struggle with heavy computational costs. In this study, we applied the micro-continuum method with an extension that incorporates multiple reactive minerals, i.e., calcite and dolomite. After validating the simulator, we studied mineral dissolution in fractured media under different transport conditions and with varying mineral portions. We observed that the mineral distribution significantly changes the flow and solute transport patterns and also influences the media's characteristics, such as the permeability-porosity relationship. Furthermore, we defined a heterogeneity index to quantify the non-uniformity of permeability caused by dissolution. Our findings indicate that despite the homogeneous distribution of minerals, variations in reaction rates produce a heterogeneous permeability field following dissolution. This study demonstrates a quantitative framework for studying the synergy between multiple minerals' dissolution and reactive transport in porous media. |
