Technology of Complex Control of Water-Oil Emulsion State in Flow

Oil for further petrochemical refining processes requires primary treatment at the fields.Primary treatment involves separating water from oil, but the formation of stable water-oil emulsions during production and in-field treatment complicates the process of further oil treatment. Determining the characteristics of complex oil emulsions is of crucial but complicated importance both for science and for many industrial applications. In this regard, it is necessary to consider current issues related to dynamic monitoring of water-oil emulsion formation. The purpose of the article is to study the technology of complex control of the state of water-oil emulsion in a flow. Research objectives: to study the theoretical aspects of emulsion formation; analysis of existing methods for monitoring the state of water-oil emulsion in a flow, determination of their advantages and disadvantages; development of proposals for improving the methodology for monitoring the state of water-oil emulsion in a flow. The scientific novelty of the study is due to the fact that the problem of preventing the formation of highly viscous emulsions in oil and gas production processes has not yet been solved, and during the implementation of the technological process, not all characteristics of the water-oil mixture are controlled, this also applies to the rheological properties of emulsions. Data on the density of the water and oil phases in the emulsion, the viscosity of the water-oil emulsion will make it possible to comprehensively assess the state of the water-oil mixture in a dynamic state and determine the occurrence of the phase inversion phenomenon in the emulsion (phase reversal). A comprehensive technique consisting of a modified scheme for monitoring the characteristics of the water-oil mixture, a method and algorithm for calculating the hydraulic resistance coefficient made it possible to determine the inversion phenomenon in the flow and calculate the optimal parameters for the technological process of in-field oil pumping.
