The aim of the work was to select the optimal reagent for the implementation of polymer flooding in the specific geological and physical conditions of the West Siberian field. For this, the solubility of polymers in the injected water and their rheological properties were studied depending on the shear rate and polymer concentration at reservoir temperature, the dynamic adsorption of polymers on the surface of the porous medium and the coefficient of additional oil displacement with polymer solutions were determined. These works were carried out in accordance with the Enterprise Standard developed by JSC VNIIneft. Based on the results of the physicochemical and filtration experiments, a polymer sample with the best performance was selected. This sample can be recommended for the implementation of polymer flooding technology in the Western Siberia field.
