TUBULAR WEAR VOLUME DETERMINATION USING STRETCH CORRECTION

摘要

Tubular stretch correction for different operational conditions is applied to determine tubular wear volume. The tubular stretch correction is applied as a function of a stretch factor comprising a varying shift factor, axial load on the tubular string, pressure effects on the tubular string, buckling of the tubular string and/or temperature effects on the tubular string. Stretch factors are taken into account to determine the correct position of wear factors along the casing string, which are ultimately used to determine the casing wear volume.
