Abstract
Using the geophysical and hydrodynamic compatibility model allows to reduce ambiguity of the solution of the inverse problem and to increase the reliability of productive layer parameters definition. It includes the parameters of permeability and porosity of the filter cake, which significantly affect the result of filtration modeling, but are not determined during the drilling. To investigate the process of formation of a mud cake, to study its properties and to determine the main parameters, the authors of the article carried out a series of experiments on a setup assembled at IPGG SBRAS, on core samples of low-permeability sandstone extracted from the YUS collector. The results of experiment with core samples from the Tevlinsko-Russinskoe and Russinskoe oil fields.
