数值模拟计算能力的快速进步吸引了研究人员致力于多孔介质反应输运领域的研究，以改善成熟储层的碳氢化合物生产过程。在水文学界，反应输运得到了很好的发展，其主要研究重点是研究含水层中地下水和污染物的运动，并量化岩石和水之间的化学反应的影响。最近，人们做出了巨大努力，将类似的模型应用于地下储层中经历多相流的石油应用。在此类系统中，热力学和化学平衡是准确描述储层中存在的流体状态的关键。本文对地球化学建模的概念以及如何将其在数学上应用于多孔介质中的石油多相流问题进行了详细而全面的回顾。我们介绍了概述实验试验中化学反应处理的关键物理概念，然后详细解释如何对化学反应网络进行数学建模以用于数值模拟应用。还显示了通过自然变量或摩尔变量公式通过一组控制方程来表征流体流动物理行为的步骤，以及简化数值算法并将其合并到现有油藏模拟方案中的方法。最后，我们提出了文献中的两个数值案例，以突出不同变量公式之间的关键差异，并评论每种方法的优点和缺点。
The rapid advancements in the computational abilities of numerical simulations have attracted researchers to work on the area of reactive transport in porous media to improve the hydrocarbon production processes from mature reservoirs. In the hydrology community, reactive transport is well developed where the main research focuses on studying the movement of groundwater and contaminants in aquifers, and quantifying the effect of chemical reactions between the rocks and water. Recently, great efforts have been made to adapt similar models for petroleum applications where multiphase flow is experienced in the subsurface reservoirs. In such systems, thermodynamic and chemical equilibrium is key in establishing an accurate description of the states of the fluids existing in the reservoir. This paper presents a detailed and comprehensive review on the concepts of geochemical modeling, and how it can be mathematically adapted to petroleum multiphase flow problems in porous media. We introduce key physical concepts outlining the treatment of chemical reactions in experimental trials and then explain in detail how a network of chemical reactions can be modeled mathematically for numerical simulation applications. The steps of characterizing the physical behavior of the fluid flow—through a set of governing equations by either natural or molar variables formulations, and the methodology to simplify and incorporate the numerical algorithms into an existing reservoir simulation scheme are shown as well. We finally present two numerical cases from the literature to highlight the key variations between the different variable formulations and comment on the advantages and disadvantages of each approach.
