Study of Properties of a Dispersant Used for Extracting Oil with High Gas-Oil Ratio

The article presents the bench test results for a dispersant manufactured by Izhnefteplast Company, which specializes in batch production of unique submersible pumping equipment for oil extraction. The submersible equipment is unique in that the working elements of the pumping equipment are made of polymeric materials unlike the conventional concept of pumping machinery for oil production. The relevance of the bench tests is determined by the fact that submersible pumping equipment faces the problem of pumping out well products containing a good deal of free gas in actual field conditions. Gubkin Russian State University of Oil and Gas has provided background to carry out bench tests of submersible pump equipment operating on model gas-fluid mixtures at various input conditions (pressure, temperature, electric motor shaft speed, feed, etc.). The bench testing is aimed at development of a procedure for dispersing efficiency determination in pre-start operation modes of submersible electrical centrifugal pumps for oil extraction.
