EFFICIENCY OF CALCULATION OF THE WATTMETROGRAM OF THE ROD PUMP UNIT DRIVE FOR OPTIMIZING BALANCING MODES

The problem of optimizing oil production has always been one of the most pressing. The article is focused on the problem of improving the energy efficiency and optimizing the operating modes of this unit for oil production using rod pumping units (SHS). The article pays special attention to accounting for a decrease in the level of oil in the well, which affects the hydrostatic pressure and the load on the pump. The results of kinematic and kinetostatic analyzes of the transforming mechanism of the rod pump unit Drive are obtained. Based on the same results, the wattmetrogram was calculated. With its help, it allows not only to control energy consumption, but also to finetune the balance mechanisms and drive systems to increase the overall efficiency and identify its weaknesses. The decrease in the oil level reduces the overall load and, accordingly, we see that the amplitude of the wattmetrogram decreases. The oil dynamogram adds dynamic vibrations to the load, complicating the power profile. Together, the two factors make the reports more realistic, which is important for the correct selection and adjustment of counterweights, engine power, and optimization of the operation of the MSS. The results in the article are obtained taking into account the characteristics of the Electromotive and reducer used in the straight-line guide converter mechanism of a Class II quadruple drive of a specific SHS unbalanced drive.
