Developing a method for the assessment of axial load in arbitrary cross-sections of the column of pumping rods Open
For accurate and objective evaluation of the stressed-strained state of a column of pumping rods (PR), it is necessary to have reliable information about axial loads that act in its cross-sections at different depth. That is why the purpos…

An experimental and theoretical method of calculating the damping ratio of the sucker rod column oscillation Open
Despite the massive use of dynamograms to identify possible faults in downhole sucker rod pumps (DSRPs), frequent analysis of the deviation of the pumping mode from the optimal mode, and attempts to determine the column load of the sucker …
