The research material was data on the laws of the distribution of failures, the actual time between failures and the main causes of failures of downhole pumping equipment of production wells of the Tarasovskoye field of Rosneft-Purneftegaz company. The study showed that oil wells equipped with sucker rod pump units have greater operational reliability.The main results of the study are the quantitative values obtained of the necessary reserve elements of pumping units at given optimal values of the probability of failure-free operation. When using the model proposed in the study for practical application in production, it is possible to carry out calculations while establishing other requirements for the optimal value of the probability of failure-free operation.
