We review theoretical and computational research, primarily from the past 10 years, addressing the flow of reactive fluids in porous media. The focus is on systems where chemical reactions at the solid-fluid interface cause dissolution of the surrounding porous matrix, creating nonlinear feedback mechanisms that can often lead to greatly enhanced permeability. We discuss insights into the evolution of geological forms that can be inferred from these feedback mechanisms, as well as some geotechnical applications such as enhanced oil recovery, hydraulic fracturing, and carbon sequestration. Until recently, most practical applications of reactive transport have been based on Darcy-scale modeling, where averaged equations for the flow and reactant transport are solved. We summarize the successes and limitations of volume averaging, which leads to Darcy-scale equations, as an introduction to pore-scale modeling. Pore-scale modeling is computationally intensive but offers new insights as well as tests of averaging theories and pore-network models. We include recent research devoted to validation of pore-scale simulations, particularly the use of visual observations from microfluidic experiments.
我们回顾了理论和计算研究，主要集中在过去 10 年，涉及在多孔介质中反应性流体的流动。重点是研究固-液界面的化学反应会导致周围多孔基质溶解的系统，这些反应会产生非线性反馈机制，从而导致渗透率的显著提高。我们讨论了可以从这些反馈机制中推断出的地质形态演变的见解，以及一些岩土工程应用，如提高石油采收率、水力压裂和碳封存。直到最近，反应性传输的大多数实际应用都是基于达西尺度建模的，其中解决了用于流动和反应物传输的平均方程。我们总结了体积平均化的成功和局限性，这导致了达西尺度方程，作为孔隙尺度建模的介绍。孔隙尺度建模计算量很大，但提供了新的见解以及对平均理论和孔隙网络模型的检验。我们包括最近致力于验证孔隙尺度模拟的研究，特别是使用微流控实验的可视化观察。
