The article describes the method of optical-electronic observation of the process of sedimentation of gel particles in the polymer-gel system. The analysis of hydrodynamic movement of gel particles in laminar and turbulent modes during the implementation of the Temposcreen technology in oil production is carried out. The effect of hydrodynamic conditions on the mobility of the polymer-gel system in well and reservoir conditions, as well as on the distribution of the dispersal gel phase in the reservoir, is considered. On the basis of the graph theory, the model of fluid flow management in the oil layer by the Temposcreen mobile polymer-gel system is presented.
