В статье рассмотрены причины отказов глубинных электроцентробежных насосных установок. На основании данных сервисных компаний исследованы зависимости наработки установок на отказ от основных эксплуатационных характеристик. Проанализированы причины и условия образования отложений неорганических солей. Рассмотрены особенности эксплуатации установок электроцентробежных насосов в условиях интенсивного солеотложения.

The given article touches upon the reasons of the failure of the downhole centrifugal electric pumping units. The analysis of the data provided by the wells repairing companies has shown the interdependence between the failure of the downhole pumping units and their main operating characteristics. The causes and the conditions of the appearance of inorganic salt precipitations in such units have also been analyzed in the article. The peculiarities of the exploitation of the downhole centrifugal electric pumping units in the conditions of intensive salt precipitation and some recommendations on how to exploit them in the best way so that to eliminate the possibility of a failure are also described here.
