The Stability

Nowadays, one of the more perspective technologies for oil recovery increase in the fields with heavy oils is formation of intrastratal emulsion. The paper presents the research on the increase of oil recovery in the fields with heavy oil via injection of combined composition based on the viscosity minimizer and surface active agent. Obtained composition allows significantly increase the stability of intrastratal emulsion, dramatically reducing the values of surface tension in the border of oil/water. The analysis of synergetic efficiency for suggested composition on the emulsion stability, surface tension and rheological properties has been carried out. More efficient concentrations of composition components have been specified. Obtained results have been justified with experiments on the replacement of high viscous oil from Galmaz field on the sand packed tubes of reservoir.

The Stability

Craik (1968) has previously examined the stability of horizontal liquid films when an air stream flows over the liquid surface and when the surface is contaminated by an insoluble surface-active agent. The present theoretical work extends this investigation to examine the role of soluble surface-active agents for cases where the liquid Reynolds number is small. This role is found to be a rather complex one which, under suitable conditions, may be either stabilizing or destabilizing.Related experimental work is described which yields results in qualitative agreement with the theoretical analysis.
