How calculate drillstring? - Answers

To calculate a drill string, you need to determine several key parameters, including the total weight on bit (WOB), the tensile strength of the drill string, and the friction losses. Begin by calculating the total length of the drill string and its weight per unit length. Then, use the appropriate formulas to assess the tensile load and any potential buckling or torsional forces. Finally, consider factors like fluid properties and wellbore conditions to ensure optimal drilling performance.
