Operation of electrical centrifugal pump units in flooded wells

Authors: A.E. Bortnikov (KogalymNIPIneft OOO), M.D. Valeev (OZNA-Management OOO)
It is shown that the operation of flooded wells, equipped with electrical centrifugal pump units , because of the formation in them of fine structures of invert water-in-oil emulsions, accompanied by a significant deterioration in the pressure characteristics of pumps, conditions of track discharge of incidentally produced water, as well as separator oil treating. For a more profound destabilization of the oil-water emulsions in wells, equipped with electrical centrifugal pump units, the development of additional measures, aimed at preventing the mixing of formation fluids in the operating elements of the pumps, is required.
