Modelling non-Darcy flow behaviour in shale rocks, composed of nanometer-sized pores and multi-scale fracture networks, is crucial for various subsurface energy applications. However, incorporating multiple physical mechanisms across numerous scales is not trivial. This work proposes an improved and practical upscaling workflow for coupling an Upscaled Discrete Fracture Matrix (UDFM) model and a pressure-dependent apparent permeability (Kapp) model to capture the effects of non-Darcy flow in multi-scale fractured shale reservoirs.

DFNWORKS 中耦合放大离散裂缝基质和视渗透率建模用于页岩储层模拟


页岩由纳米级孔隙和多尺度裂隙网络组成，对页岩中的非达西流动行为进行建模，对于各种地下能源应用至关重要。然而，在多个尺度上整合多种物理机制并非易事。这项工作提出了一种改进的实用放大工作流程，用于耦合放大离散裂缝矩阵 （UDFM） 模型和压力依赖性视渗透率 （Kapp） 模型，以捕获非达西流在多尺度裂缝页岩储层中的影响。
