Web20 jun. 2024 · Therefore, the following equation represented the phenomena: The resistance R is made up of filter cloth Rf and that of cake Rc which may be assumed proportional to the weight of the cake. Where: α = specific resistance of the cake (m/kg) c = weight of solids per volume of liquid (kg/m 3) μ = viscosity (N sec/m 2) P = pressure difference (N/m 2) Webtration theory. Thus, the one variable for cake filtration of constant pressure is the mass of solid in filter cake per unit filtration area W in Eq. (1). At the moment of starting filtration, there is no cake on a filter medium. The mass of cake increases as filtration proceeds, and this decreases the rate of filtrate dV/dt by Eq. (1). Eq. (1 ...

Web22 dec. 2024 · Filter cake properties such as permeability, porosity, toughness, thickness, structure, particle size distribution are the key elements that influence the fluid invasion into the drilled formations, and therefore, they affect the formation productivity (Ba geri et al., 2013a; Li and He, 2015 ). Webthat the sedimented particles are considered as a part of filter cake. Thus the mass of cake per unit filter area, W, was cal-culated as the sum of the amount of cake formed by filtra-tion, i.e. rSV/(1-S/S c), and the amount of sediment, rSv st/ (1-S/S c). Here, vs is the sedimentation velocity. If this would flow pure 8 https://threehome.net
