The subject of research is oil-water emulsion that forms during oil production process.
This work is aimed at studying causes of oil-water emulsion formation and stabilization factors.
Two-phase fluid behavior during oil production with application of various technologies has been studied. Sources of flow turbulence in oil-production equipment and surface facilities which cause oil emulsification have been identified. Dependence of oil-water emulsion stability on various factors has been determined.
This study is essential when selecting oil field development technology or oil dehydration method, as well as when employing various oil well stimulation techniques.
