Annotation:

The authors of the article describe the process of a theoretical model development for assessing the quality of downhole sucker-rod pump (DSRP) elements, present calculations of the valve pair indicators as well as consider the possibility of automating the quality control of the DSRP operation on the basis of the developed mathematical model. The presented approach will allow optimizing the operation of pump elements, which will positively influence the main quality indicators of DSRP, such as filling factor, reliability and efficiency. Special attention is paid to integration and automation of DSRP quality control into modern automation systems, including frequency regulation, SCADA-systems and digital twins. The model accounts for the change of pressure and liquid flow dynamics for optimizing the hydraulic resistance of the valve pair as well as adapts the Taguchi concept to minimize the disturbance factors impact on equipment operational life. It is shown that the introduction of digital doubles integrating the developed model allows predicting the wear of DSRP elements and increasing the inter-repair period of wells by analyzing real production data.
