ABSTRACT
In the presented article, the analysis of the effect of the dynamic load falling on the polished rod of the sucker rod pump unit on the normal function of the operating unit during the oil extraction process was carried out. The general formula for the damage caused by the impact of the pump's wellhead packing seal has been derived. The dependence graph of damaged work on the length of the packing seal and the Poisson's ratio of the material was made.
Due to the dynamics of the frictional force generated in the packing seal of the stuffing box appropriately located below the suspension point of the rods, its forced cyclic movement occurs as a result of the impact transmitted to the system which consists of an incompressible fluid column, and the elastic rods. This requires the investigation of the dynamics of the rod pump associated with the probability of unpleasant situations such as the possible resonance occurrence in the specified system, the time between repairs, and the reduction of the working coefficient of the pump, in this regard.
At the same time, the questions such as the coefficient of friction depending on the selection of the material of the packing seal, the reduction of the dynamic accumulation of the load on the system, and the saving of electric energy are also important. It needs to be considered that the operation process is accompanied by a certain energy loss. It should be taken into account that even a small reduction in energy loss can manifest great economic benefits. It should be noted that some issues encountered in the process of operation of oil wells through the rod pump and depending on certain arguments affecting this process were also resolved by those experts.
