The effect of eccentric tension on the corrosion-fatigue resistance of pump rods
Complex operating conditions of sucker rods in wells are caused by the action of high alternate loads and corrosive-active technological environments. The most severe load conditions of sucker rods are associated with eccentric tension. In order to predict the performance of operated sucker rods, simulation and calculation modeling of the stresses which will occur in them under real operating conditions is proposed. It is experimentally demonstrate that under eccentric tension of rods, their fatigue life decreases, and the fatigue characteristics of rods made of 20N2M and 15N3MA steels become practically the same after their 5 years of operation.
