Abstract
It was established that in addition to the variable axial forces on a curved section of the well column tubing may be exposed to both static and cyclic bending moments. Last arise from additional tensile force of the weight of the liquid column acting on the receiving valve by driving down the point of suspension rods. These bending moments can cause fatigue tubing. The method can be used to calculate the normal stresses and predicting fatigue durability tubing during their operation in curved sections of wells.
