Diagnosis of the rheological properties of oil emulsions considering watercut and temperature factors

G.A. Zeynalova

It is well known that one of the factors adversely affecting the operational efficiency of infield technological oil pipelines is persistent oil emulsions formed due to the oils watercut. These hardly demulsifible emulsions with abnormal rheological features show non-Newtonian properties. Depending on the temperature and watercut degree, the viscosity of these emulsions varies widely. The specification of viscosity and other physical-chemical properties in oil-field experience is carried out via laboratory testing of oil samples according to the standards. Based on the roto-viscosimetric studies of oil samples with various temperatures, an empiric formula for the specification of oil emulsions viscosity depending on watercut degree is offered. It was defined that the offered formula enables with permissible error to specify the viscosity of abnormal emulsions considering the changing watercut and temperature aspects.
