SYSTEMS AND METHODS FOR DETERMINING THE MOMENTS AND FORCES OF TWO CONCENTRIC PIPES WITHIN A WELLBORE

摘要

A wellbore may contain two concentric pipes, the external pipe designated the "casing" and the internal pipe designated the "tubing". The invention comprises systems and methods for determining the bending moment and shear force of tubing and casing, when the tubing buckles and contacts the casing, thus providing an improved method for analyzing concentric buckling pipes.
