Abstract Carbonate rocks display complex pore textures with heterogeneities that extend over several length scales. Identifying and capturing the significant pore space properties in a computationally tractable model is therefore nontrivial. Pore-scale models bridge predictions of transport properties from sub-pore to core scale and attempts have been made to render such methods cost-effective. This chapter reviews several methods for fabricating pore-scale models of carbonate rocks and discusses approaches to simulating their fluid flow and solute transport properties. The advantages and limitations of each method in reducing the reservoir development uncertainties are explained. We argue that pore-scale models can play an important role in predicting the petrophysical properties of carbonate rocks. Even more importantly, they provide sensitivity analyses of pore-scale features on macroscopic transport observations and offer explanations for anomalous flow behaviors.

碳酸盐的孔隙尺度模拟

摘要 碳酸盐岩表现出复杂的孔隙结构，具有跨越多个长度尺度的非均质性。因此，在计算上易于处理的模型中识别和捕获重要的孔隙空间属性并非易事。孔隙尺度模型桥接了从亚孔隙到核心尺度的输运特性的预测，并且已经尝试使这种方法具有成本效益。本章回顾了几种制作碳酸盐岩孔隙尺度模型的方法，并讨论了模拟它们的流体流动和溶质传输特性的方法。解释了每种方法在降低油藏开发不确定性方面的优点和局限性。我们认为孔隙尺度模型可以在预测碳酸盐岩的岩石物理性质方面发挥重要作用。更重要的是，
