Today in Ukraine, the necessary intervals between controls, their content and volume are formed on the basis of statistical data. These statistics do not take into account the specific features of a particular SRPU, the real conditions of its operation, but only the SRPU type of SRPU type. The monitoring of SRPU, based on such monitoring and control, cannot be objective. Objective technical monitoring and monitoring of the state of the system requires that the actual real-time state be monitored, taking into account the factor analysis, which will significantly increase its turnaround time and reduce operating costs. A four-view classification of the main methods for controlling a sucker rod pumping unit (SRPU) has been proposed. The essence of each control method of a SRPU is disclosed. Made their comparative analysis and opportunities. The vibration control and monitoring of the pumping unit gearbox of the SRPU is considered in more detail. The strategy and experiment planning of the reduction gearbox of a SRPU has been developed using factor analysis. An experimental model installation of a SRPU has been developed and created, which allows implementing the developed strategy to study the effect of gearbox defects, its operating conditions and the influence of other elements of the SRPU on the vibration characteristics of a wellbore well pumping unit. It is shown that there can be no objective control when the necessary intervals between controls, their content and volume are formed on the basis of statistical data, without taking into account the specific features of a SRPU and the real conditions of its operation, but only the type is taken into account. An objective technical monitoring of a SRPU has been proposed, which will significantly increase its overhaul mileage and reduce operating costs.

Keywords:

monitoring, pumping unit, factor analysis, vibration characteristics, reduce operating costs.
