The mechanism of the action of fluid loss control additives in cementing oilwell operations is principally the reduction of permeability of the cement filter cake. From filtration equations physical characteristics as porosity of the cement filter cake were investigated and compared with experimental data. A good correlation is observed when no adsorption is involved. The smallest pore diameter for obtaining an efficient control of fluid loss is shown to be of the same order of magnitude as the gyration radius of used macromolecular chains.
