ELECTRIC SUBMERSIBLE PUMP INTERNAL FLUIDICS SYSTEM

摘要

An electric submersible pump (ESP) can include a shaft that includes an axis; a pump mechanism operatively coupled to the shaft; an electric motor that drives the shaft and that includes an electric motor housing that defines at least a portion of a dielectric oil chamber; and a fluidics system that controls flow of well fluid within the electric motor housing to reduce contamination of the dielectric oil.
