The paper presents the results of studies on the estimation of quantitative and qualitative impact of fluid pumping rate of sucker-rod pumps on the production parameters, as well as on the frequency of repair and overhaul period of the wells on the late stage of field development. The distribution of speed rates of pumping by wells and dependences of flowrates, flooding and coefficients of pumping capacity from pumping delivery have been analyzed based on the actual field data as well. The studies showed faster growth of water discharge compared to the oil, as well as reduction of oil delivery rate with increasing pumping speed. It is justified that the overhaul period reduces and the frequency of repair increases with raising pumping speed. The study results enable to make conclusions on the practicability of pumping speed limitation, as well as the necessity of measures towards flooding and reasonable selection of mode parameters for sucker-rod pumping during the exploitation of reviewed field.
