Abstract: To protect the electrical submersible pump from the harmful effect of free gas when pumping out production fluid the current research activities are focused on the study of construction and technological characteristics of mechanical disperse systems. These are typically devices for gas phase fragmentation in the oil-gas mixture in the suction pipe. One of the technical solutions can be dispersing stages integrated into the electrical submersible pump unit (ESPU). Gubkin University specialists have developed the method of testing disperse devices to determine the optimal ESPU design for specified geological conditions.
