摘要
Methods and computer-readable media are provided for determining design parameters for oil well casing and tubing to prevent buckling in deviated wellbores. Well parameter data including tubing size, tubing weight, well depth, and well geometry is obtained and may be utilized to calculate parameters for predicting the movement of tubing near a packer or centralizer in the deviated wellbore based on the received well parameter data, predicting a total bending moment near the packer or centralizer, predicting a maximum bending stress near the packer or centralizer based on the total bending moment, and predicting the minimum axial force necessary to initiate buckling due to friction, and predicting the onset of buckling for the connection of tubing of different sizes. After the parameters have been calculated, they may be utilized in the design of the oil well casing and tubing to prevent buckling in the deviated wellbore.
