### Investigation of the Mechanism of Sediment Formation in Sediment-Gelling Compositions
Graphical dependences are presented in Figure 5. Figure 6 reveals the distributions of these parameters in a two- and three-dimensional image. A comparative analysis of these results makes it possible to more clearly follow the change in rheological constants and the nature of the compositions used in the experiments associated with this. The figures clearly show different areas characterizing the properties of the compositions associated with flow and deformation, i.e., Newtonian or pseudoplastic nature. These parameters, called \"rheological constants\", are characterized by certain values that do not depend on the conditions for their measurement or on the design of measuring instruments. Using the data obtained from a rotational viscometer, according to the formula (\(\mu_{E}=k\cdot\dot{\gamma}^{t-1}\)) given in [1], the effective viscosity values for the studied SGCs were calculated. The work [1] provides an analysis of experimental observations, which showed that the effective and Newtonian viscosities of SGCs prepared on fresh water decrease with a rise in alkali concentration, while the same properties of SGCs prepared on combined formation water increase. \begin{table}

At the same time, the results of the studies showed that the rheophysical properties of SGCs, for a number of reasons, depend on the mineralization of the solvent, the concentrations of caustic soda and polymer, the shear rate, and the temperature [1]. At a low polymer concentration in SGCs, the distance between macromolecules is large compared to their sizes. Therefore, when a polymer is added to a Newtonian fluid (solvent) to a certain concentration, the viscosity of the SGCs will increase, and the linear relationship between shear stress (t) and shear rate (y) will not be violated [1]. However, when a certain concentration is reached, this linear dependence will be violated, which will lead to an anomaly in viscosity. In this case, SGCs will exhibit pseudoplastic properties, and their effective viscosity will decrease with increasing shear rate (Table 4, at ionomer concentrations \"L\" of 0.5; 1%).
