| Abstract: | The article provides a justification for the gel-forming composition for well water insulation based on sodium silicate, polyacrylamide (PAA), and chromium acetate, with increased strength characteristics due to the introduction of a dispersed additive, rice husk, which simultaneously exhibits viscoplastic and viscoelastic properties. Oscillation testing is used to determine the elastic modulus (G') and loss modulus (G"), the linear measurement range, and the quantitative determination of the viscoelastic and viscoplastic properties of the hydrogel, based on the interpretation of creep and recovery study results using the mechanical models of Maxwell, Kelvin–Voigt, and Burgers, which are successfully applied to the behavior of polymer systems. It is established that when approximating experimental measurements, one link of the Kelvin–Voigt model is not sufficient; therefore, the Burgers computational model is recommended, which corresponds to two relaxation times of a viscoelastic medium due to two types of crosslinking: ionic (from the bonding of the chromium ion with the polymer) and flocculation (from the flocculation of dispersed rice husk particles by polymer macromolecules). Filtration studies performed on a model of an ideal crack with different openings (from 0.01 to 0.1 cm) establish that the introduction of rice husk into the hydrogel composition increases its strength characteristics and resistance to mechanical destruction. In the case of filtration through a 0.1 cm slit, there is no noticeable difference in the rheological behavior of the hydrogel with and without rice husk, except for some strengthening of the gel during filtration at low shear rates. A mechanism responsible for the behavior of the hydrogel with this dispersed additive in cracks of various openings is proposed. The application of the developed hydrogel composition is promising in real fractured reservoirs through which water flows to the well and, as a consequence, causes flooding. [ABSTRACT FROM AUTHOR] |
