So the nature of the
ground produced fluid naturally becomes more complex [2],
the degree of oil-water emulsion for carrying chemical
flooding agents is significantly increasing or the emulsion
stability after a long time is enhanced, and finally many
problems brought about constraint normal production such as
the increase of energy consumption in ground processing
systems, the instability of treatment facilities, increasing
dosage of treatment agent and process difficulty, the result is
not satisfactory and so on.
