Abstract
The task of this work is to study the effect of a reagent of various concentrations on the physical and chemical properties of high-viscosity oil and to select the reagent with the most effective indicators for reducing the viscosity in carbonate reservoirs of medium carbon. The results of the study showed that the reagent was adsorbed on the structure-forming components of the oil and weakened the interaction between them, which led to a decrease in the viscosity of the oil. The greatest reduction in oil viscosity was achieved by introducing 2% of the reagent into the oil emulsion (a decrease in viscosity by 51 mPa * s or 6%), and 3% of the reagent into the dehydrated oil (a decrease in viscosity of 32 mPa*s or 4.9%).
Materials and methods
The gas chromatography method using the "TotalChrom" software package is used as a separation method based on the distribution of the substance between the mobile and stationary phases. SARA analysis was
used to separate the oil into components under laboratory conditions.
