Background

The permeability coefficient is also called hydraulic conductivity (hydraulic conductivity). In isotropic media, it is defined as the unit flow rate per unit hydraulic gradient, representing the ease of passage of fluid through the pore framework, and is expressed as: k rho g/η, where k is the permeability of the pore medium and is only related to the properties of the solid framework and k is the permeability coefficient; eta is dynamic viscosity coefficient; ρ is the fluid density; g is the acceleration of gravity. In anisotropic media, the permeability coefficient is expressed in tensor form. The greater the permeability coefficient, the stronger the rock permeability. The permeability coefficient of the strong permeable coarse gravel stone layer is more than 10 m/day and night; the permeability coefficient of the weak permeable subsoil is 1-0.01 m/day and night; the clay permeability coefficient of the water-impermeable layer is less than 0.001 m/day and night.
