At present article were used the results of theoretical study of radial flow of viscosity-plastic dispers system in a plain capillar. On the base of generalization of results of theoretical investigations, the expressions for determining of flow rate and velosity distribution for any liquid in any crack with openings < kp were obtained. Fluid flow rate calculation method in microcracks also were suggested. In this case experimental and calculation values of liquid flow rate coincide with the acceptable accuracy. Theoretical investigation of viscosity-plastic dispers systems radial flow in capillary agree with calculations based on experimental results. The fact, in its turn, proves the identity of above mentioned practical approach with the results of experimental study provided in microslits. Developed experimental method of study of flat-radial liquid flow in microcrack, in what follows by means summarizing experimental researches subject to system crack different forms orientations, could be used for liquid filtration estimation in only fractured zone.
