FATIGUE ANALYSIS PROCEDURE FOR DRILL STRING

摘要

A method, system, and computer readable medium for management of fatigue life are disclosed. Management of fatigue life includes partitioning a drill string into sections, calculating a stress value for each section. From the stress value, an equivalent stress amplitude is calculated for each section, and a fatigue life consumption is calculated for each section, and a fatigue life consumption value in each section is computed. The fatigue life consumption value across the sections is aggregated to obtain an aggregated fatigue life consumption value.
