Key words: electric centrifugal pump unit, batch scheme of assembly, solid inclusions, mechanized oil production, wear resistance, low-yield stock, unification.
Development and comissioning of immersion oil-production equipment with the increased resistance to the action of abrasive particles, whose construction is maximally standardized with the series oil production equipment, used in Surgutneftegas OJSC, are considered. The developed construction at present passes the procedure of obtaining patent on useful model. The electric centrifugal pumps, manufactured on the developed project, are applied in industry at the fields of Surgutneftegas OJSC. Their time to failure according to the results on November 2014 is by 22- 24% higher than mean time to failure of series equipment, and for the wells, complicated by the increased quantity of solid particles in the formation fluid, an increase in the operating time exceeds 100%.
