Abstract

The technology of restoring sucker rods has been developed and tested on the example of 20N2M steel. At high levels of bending stress applied to samples from restored sucker rods, fatigue life in the environment of formation water was shown to increase by almost an order of magnitude compared to samples from an unused rod. The developed technology makes it possible to extend the service life of sucker rods and the periods between scheduled measures for diagnosing their state.
