文章摘要
Formation and flow of emulsions in porous
media are common in all enhanced oil recovery techniques.
In most cases, oil-in-water (O/W) emulsions are
formed in porous media due to oil–water interaction. Even
now, detailed flow mechanisms of emulsions through
porous media are not well understood. In this study,
variation of rate of flow of O/W emulsions with pressure
drop was studied experimentally, and rheological parameters
were calculated. The pressure drop increases
with an increase in oil concentration in the O/W emulsion
due to high viscosity. The effective viscosity of the
emulsion was calculated from the derived model and
expressed as a function of shear rate while flowing
through porous media. Flow of O/W emulsions of different
concentrations was evaluated in sand packs of
different sand sizes. Emulsions were characterized by
analyzing their stability, rheological properties, and temperature
effects on rheological properties.
