Stress Analysis and Applications of Sucker Rod in Deviated Wells

Article Preview

Abstract:

The sucker rod of artificial lift system in a deviated well is very complicated. This paper applies structural mechanics to analyze the distributed characteristics of stress along the sucker rod in a deviated well and builds a reliable model for stress calculation. Moreover, the model designs the sucker rod without neglecting the effects of the reaction forces and bending forces under the condition of 3D structure. Particularly, as for deviated wells with high kickoff point and long inclination paragraph, the model shows better calculation accuracy and reflects the actual local stresses.
