摘要

根据裂缝的分形特征,本文将裂缝中流体的流动路径视为一个粗糙的毛细束。结合有效应力对岩石裂隙渗流的影响,建立了考虑有效应力的粗糙岩石裂隙渗透率分形模型和归一化渗透率模型。研究了有效应力和相对粗糙度对裂缝渗透率的影响,以及归一化渗透率与杨氏模量、泊松比的关系。研究结果表明,粗糙裂缝的归一化渗透率与相对粗糙度、泊松比和有效应力成反比,而与杨氏模量成正比。并将本文模型与已有模型和实验数据进行对比分析,结果表明本文模型能有效描述应力条件下粗裂缝内流体的渗流特性。

Fractal study of fracture permeability characteristics in porous media based on rough capillary bundle model and stress effect

In accordance with the fractal characteristics of fractures, the flow path of fluid in fractures is regarded as a rough capillary bundle in this paper. Combined with the influence of effective stress on seepage in rock fracture, the fractal model of permeability and the normalized permeability model in rough rock fracture considering effective stress are established. The effects of effective stress and relative roughness on fracture permeability and the relationship between normalized permeability and Young’s modulus, Poisson’s ratio were investigated. The findings reveal that the normalized permeability in the rough fracture is inversely related to both relative roughness, Poisson’s ratio and effective stress while exhibiting a direct proportionality to Young’s modulus. In addition, the model presented in this paper is subjected to a comparative analysis alongside existing models and experimental data, which shows that the model in this paper can effectively describe the seepage properties of fluid within rough fractures subjected to stress conditions.

期刊介绍: GENERAL OBJECTIVES: Computational Particle Mechanics (CPM) is a quarterly journal with the goal of publishing full-length original articles addressing the modeling and simulation of systems involving particles and particle methods. The goal is to enhance communication among researchers in the applied sciences who use "particles'''' in one form or another in their research. SPECIFIC OBJECTIVES: Particle-based materials and numerical methods have become wide-spread in the natural and applied sciences, engineering, biology. The term "particle methods/mechanics'''' has now come to imply several different things to researchers in the 21st century, including: (a) Particles as a physical unit in granular media, particulate flows, plasmas, swarms, etc., (b) Particles representing material phases in continua at the meso-, micro-and nano-scale and (c) Particles as a discretization unit in continua and discontinua in numerical methods such as Discrete Element Methods (DEM), Particle Finite Element Methods (PFEM), Molecular Dynamics (MD), and Smoothed Particle Hydrodynamics (SPH), to name a few.
