This study presents a mathematical method for modeling the three-dimensional dynamic configuration of sucker rod strings as they move through actual wellbore trajectories during reciprocating pumping operations. The construction method accounts for the complex spatial movements and deformations of the rod string within the wellbore geometry during oil extraction. This enables more accurate prediction of rod string behavior, stress distribution, and contact forces between the rods and wellbore walls.
Why it matters
The method provides oil field operators with improved tools for predicting rod string wear, optimizing pump operation, and preventing costly equipment failures in directional and horizontal wells. Better understanding of dynamic rod configurations can extend equipment life and reduce maintenance costs in artificial lift operations.
