Shale gas storage and permeability space is between nanometers micrometers has strong multiscale characteristics, resulting in highly complicated shale flow. Therefore, the development of needs to clarify seepage mechanism establish a flow model equation that can analyze In this paper, based on single nanotube model, combined with Weiyuan-Changning demonstration zone target layer Longmaxi forma...

The seepage failure induced by high water pressure along the fault structural plane is one of main factors for deformation and underground caverns. Based on pipe domain model with discrete element particle flow method, law conservation introduced, renewal equation improved connecting change mechanical volume in timestep effective stress. analysis fractured rock mass established, sample used to ...

Hierarchical social networks appear in a variety of contexts, such as the on-line social network Twitter, the social organization of companies, and terrorist networks. We examine a dynamic model for the disruption of information flow in hierarchical social networks by considering the vertex-pursuit game Seepage played in directed acyclic graphs (DAGs). In Seepage, agents attempt to block the mo...

The safety of underground engineering projects is significantly influenced by groundwater. One the key complexities identifying primary seepage paths within rock formations, understanding patterns seepage, and determining effects fracture parameters on fluid movement inside mass. To address these issues, a probabilistic model constructed for random fractures using finite element method, reflect...

Received: December 25, 2016 Revised: January 09, 2017 Accepted: March 07, 2017 Abstract: Introduction: Due to the fact that the model experiment can simulate the flow process and movement law of fluid during the seepage experiment, seepage model experiment was widely applied to study the hydraulic characteristics of rock-soil mass and transportation of ground water and pollutants. While due to ...

Water flooding microscopic seepage experiment is an effective method to study the microvadose mechanisms as well as the distributions of remaining oil. Throughout the experiment the quantitative description of the porous medium fluid flow parameters such as porosity, oil saturation and so forth is crucial. A quantitative analysis method is proposed via image processing, including image preproce...

The classical formulation of the coupled hydroelectrical flow in porous media is based on a linear formulation of two coupled constitutive equations for the electrical current density and the seepage velocity of the water phase and obeying Onsager’s reciprocity. This formulation shows that the streaming current density is controlled by the gradient of the fluid pressure of the water phase and a...
