TUBULAR WEAR VOLUME DETERMINATION USING ELASTICITY CORRECTION

摘要

Tubular elasticity is applied to determine tubular wear volume. In general, a torque and drag model is applied to calculate the dynamic stretch of the inner tubular string (e.g., drill string). The dynamic stretch is then integrated into a casing wear model to improve the accuracy of the calculated wear and its corresponding position along the outer tubular string (e.g., casing string).
