Essay

The dissertation is devoted to guestions of oil-well pumping unit equipment protection of corrosion fatigue and formation of paraffin. It was showed that torque effect applied at the top of string impact negatively on its stability. It is defined the value of the torque created by the protector wings for an additional torque on the rod string by the interaction with the fluid flow in the tubing. It is developed a calculation model for the synthesis of kinematic parameters of sucker rod string worm rotator actuator sucker rod of continuous operation. It was established that sucker rod body coating with fiberglass tapes increases corrosive fatigue resistance by operating in corrosive.
