“…When the drilling fluid contains particles of different sizes, the larger particles of the drilling fluid form the skeleton of the filter cake and the smaller particles can migrate and deposit within the porous cake formed by the large particles. Simultaneously, the cake may undergo a compaction process by the effect of the fluid drag as the suspension of smaller particles flow through the cake [5]. Polymer additives are capable of intercalating a large amount of water with their stretch of long chains.…”

A b s t r a c tThe objective of this work is to provide a new insight into the spatial distribution of physical, chemical structure of the filter cake layer. The spatial distribution was characterized by various analytical techniques, including high-temperature high-pressure (HTHP) fluid loss test, scanning electron microscopy (SEM), energy dispersive spectrum (EDs), particle size distribution (PSD), fluorescence test, pore size, porosity, density, water and polymer content measurement etc.. Specific cake resistance and the permeability of the filter cake were measured. The results obtained show that the spatial distribution of filter cake layer structure changes from the top layer to bottom layer. A large amount of deformable colloid particles in the filter cake layer is beneficial to the reducing of the cake permeability. The polymer and water content of the cake layer decreased from the top cake layer to the bottom cake layer. Through the SEM images, cake layer was found to have a loose outer surface when compared with the bottom cake layer.

“…For instance, considering a constant concentration of the feed and given a cake capturing practically all particles, it can be observed that the cake thickness grows slower than linearly while the pressure drop curve exhibits a superlinear behavior. One explanation is the compaction of the cake due to pressureinduced mechanical compression [5][6][7].…”

“…The incompressible filter cake is completely built by the filter-aid, which allows describing an evolution equation based on the mass balance of filter-aid at the surface. Models for compressible filter cake were developed in [5][6][7]. There, the small particles can penetrate the cake layer, but all the larger particles are completely deposited at the surface.…”

Combined Depth and Cake Filtration Model Coupled with Flow Simulation for Flat and Pleated Filters

Filtration processes characterized by initial depth filtration, followed by a stage during which the cake acts as both a depth and surface filtering medium are studied. Such phenomena can occur especially for polydisperse dust. Based on onedimensional depth filtration modeling, a combined depth and cake filtration model is formulated and coupled with the fluid flow. The evolution of flow resistivity and filtration efficiencies is investigated in the case of relatively dilute suspensions and constant flow rates. Numerical simulations of single-pass experiments are performed for both flat and pleated filter media. The model presented here is able to predict a nonlinear pressure drop for incompressible filter cakes due to the reduction of pore volume by particle deposition in the cake region.

Simultaneously, the cake may undergo a compaction process by the effect of the fluid drag as the suspension of smaller particles flow through the cake [4]. The particle size distribution (PSD) of solids in the filter cake is determined using a conventional laser light scattering instrument [5] and using a laser diffraction method [6].…”

ELMİ ƏSƏRLƏR • PROCEEDINGS • НАУЧНЫЕ ТРУДЫ 30 №1Filter cake formed by large particles has an increased porosity, and also, a greater permeability. The objective of this work is to provide a comprehensive review of the microscopic structure and elementary composition, particle size distribution, and polymer concentration in different layers of the filter cake to reveal the mechanism which led to the changes of structure of filter cake. The effect of inorganic salt on the structure of filter cake has been conducted. The results obtained show that a high level of electrolyte contamination has facilitated the flocculation of drilling fluid. The gel strength becomes too weak to suspend larger particles, and they are easier to deposit in fluid with electrolyte contamination. As a result, the particle size of the bottom layer of the filter cake is larger than that of middle layer and top layer. It is possible to improve the salt tolerance of brine based drilling fluid, in other words, provide a plentiful supply and homogeneous distribution of deformable colloidal particles which are formed by bentonite and polymers in the filter cake. The deformable colloidal particles plug pores of various sizes, increasing the percolating resistance of the filter cake and reducing the velocity of filtration.
