ABSTRACT: In order to study the profile control characteristics of emulsions in porous
medium, the heterogeneous experimental model was established, by which
the experimental scheme was designed with different permeabilities, matching
degree of particle size and concentration of emulsions. Based on experimental
results of physical simulation, the concept of distributing rate and
changing coefficient was introduced to quantitatively evaluate the profile
control characteristics of emulsions. The results of the study show that, as the
permeability ratio and emulsion concentration increase, the profile control
characteristics of emulsions will enhance. The profile control characteristics
of emulsions will be the best. The profile control scheme with emulsions was
implemented in Bohai X oil field, The research results can be used for reference
to design the profile control scheme in Bohai heterogeneous reservoir.
