摘要

本文提出了一种时间明确、完全耦合的水力机械模型,用于模拟断裂多孔介质中的两相流动过程,并考虑了地质机械效应。本文开发了两种求解器,并考虑了水力/力学的相互影响:(i) 一种新型有限体积离散断裂矩阵模型(FV-DFM),用于模拟通过孔隙和裂缝的两相流动;(ii) 一种有限离散元组合方法(FDEM),用于模拟力学响应(如变形和断裂)。特别是在基质-裂缝界面应用了一种新型两相交换流模型,克服了现实捕捉裂缝间不连续性(如压力、饱和度和法向通量)的困难。同时,采用了裂缝和基质流的非均匀时间步长,在保持精度的同时提高了计算效率。根据现有结果对所提模型的性能进行了验证,并将其应用于考虑到裂缝传播的实际注水过程。结果表明,该模型可以很好地预测裂缝储层中的两相流动过程(如压力/饱和度场、储层采收率),并揭示了 HM 对流动过程的重要耦合影响(如应力相关渗透率和裂缝扩展),对油气储层和二氧化碳地质封存具有重要意义。

Coupled hydro-mechanical two-phase flow model in fractured porous medium with the combined finite-discrete element method

This paper presents a time-explicit, fully coupled, hydro-mechanical model to simulate the two-phase flow process in fractured porous media, considering the geomechanical effect. Two solvers are developed, and mutual hydro/mechanical interactions are considered: (i) a novel finite volume discrete fracture–matrix model (FV-DFM) for two-phase flow, through both pores and fractures; and (ii) a combined finite-discrete element method (FDEM) for mechanical responses (e.g., deformation and fracturing). Particularly, a novel two-phase exchange flow model is applied at the matrix–fracture interface, which overcomes the difficulty in realistically capturing the discontinuity (e.g., pressure, saturation, and normal flux) across fractures. Meanwhile, non-uniform time steps of fracture and matrix flow are adopted to improve computational efficiency while maintaining accuracy. The performance of the proposed model is validated against existing results and applied to a practical waterflooding process considering fracture propagation. Results show that the model can well predict the two-phase flow process (e.g., pressure/saturation field, reservoir recovery) in fractured reservoirs, and reveal the important HM coupled effect on the flow process (e.g., the stress-dependent permeability and fracture propagation), with important implication for hydrocarbon reservoirs and CO2 geological storage.
