Abstract. An integral task for the oil and gas industry is the analysis of the composition and characteristics of the oil and gas flow in the processes of oil and gas production. Important parameters requiring analysis and control are water concentration, dispersion of emulsions, viscosity, density, content of asphaltenes, resins and paraffins.
The problem lies in measuring the amount of oil and its physico-chemical properties during production, since the well fluid often contains gas and foreign components that form ballast. The most serious complication in oil and gas production processes is the formation of stable high-viscosity oil-water emulsions caused by the phenomenon of phase inversion. This leads to the formation of a “plug” of “solid” emulsion in the flow, which creates significant resistance and increases the risk of ruptures in pipelines.
The analysis showed that at the moment there are no methods and instruments for monitoring the properties and state of water-oil emulsions that affect the hydrodynamic flow regime. Emulsion viscosity, drag coefficient and phase inversion are key properties that need to be determined and controlled to ensure optimal technological processes in oil and gas production.
Keywords: water-oil emulsion, phase inversion, hydrodynamic regime, characteristics control, methods and control devices.
