The article considers the results of the study on the selection of chemical reagents to improve the rheological properties of the oil emulsion of the Kondinskoye oil field during transportation and dehydration of the emulsion. The studies have been carried out on an artificial emulsion. We describe a method of determining demulsifying activity of a reagent at a certain temperature mode of a preliminary water discharge plant. In addition, we give the results of the study with various chemical reagents, select the optimal mode of emulsion preparation. This experiment was conducted in order to select the most effective demulsifiers to improve the technology and economics of the field and transportation process. The optimal choice of type of demulsifier, mode of its application and places of entry guarantee high quality of oil preparation. The following demulsifiers could be used in the process: DE-4, DE-6, and DE-9. The result of using these reagents is an optimal reagent flow rate per ton of fluid and a maximum amount of water separated from the emulsion over a certain time.
