The article presents the study of the relationship between permeability, pressure gradient and filtration coverage coefficient by means of empirical dependencies. Empirical dependences were obtained based on the results of laboratory studies of oil filtration on samples of low-permeable core taken from the AC3 reservoir of the V.N. Vinogradov field. For the studied core samples, the values of the filtration coverage coefficient relative to the entire open porosity, as well as its oil-saturated part separately, were calculated. It is revealed that pressure gradients increase brings increase of the filtration coverage coefficient by liquid, which should be considered when developing hydrocarbon deposits with low-permeable reservoirs.
