WebAimed at the multi-scale fractures for stimulated reservoir volume (SRV)-fractured horizontal wells in shale gas reservoirs, a mathematical model of unsteady seepage is established, which considers the characteristics of a dual media of matrix and natural fractures as well as flow in the large-scale hydraulic fractures, based on a discrete-fracture model. Multi … WebFLOWNET is a simple computer program developed to calculate hydraulic and topographic gradients for two-dimensional surfaces. Flow rates are calculated for saturated and unsaturated conditions based upon application of Darcy's law and the exponential hydraulic conductivity equation. The FLOWNET program can be applied to evaluate flow in ...
WebOct 6, 2024 · Fractured seepage is an important factor affecting the interface stability of rock mass. It is closely related to fracture properties and hydraulic conditions. In this study, the law of seepage in a single fracture surface based on modified cubic law is described, and the three-dimensional discrete element method is used to simulate the dam … WebThe invention also discloses a design calculation method of the water reservoir. With the arrangement of the transverseseepage collecting pipes and the vertical seepage collecting pipes which are criss-crossed and communicate in the seepage discharging layer, water in the seepage discharging layer is automatically collected into the water ...
WebApr 2, 2024 · This is because the intensity of heat exchange between the injected fluid and the reservoir under the same properties of the injected fluid depends mainly on the seepage velocity of the fluid, and the seepage velocity is the same under the same flow rate of the injected fluid and the same overflow area, so the heat extraction performance is ... WebCivil Engineering questions and answers. Given the flow net in Figure 4, calculate pressure heads at points A to H, the quantity of seepage, and the hydraulic gradient in point X. The soil permeability is k = 5×10−4 m/s. Question: Given the flow net in Figure 4, calculate pressure heads at points A to H, the quantity of seepage, and the ...
WebUsing that flow net we may calculate our desired quantities like seepage through soil. But our soil is not isotropic and its anisotropic. If we are, somehow, able to convert our equation number 1 into a Laplace equation, we may find the quantity of seepage through the soil of an earth dam with anisotropic properties.
