METHOD OF MEASURING STICK SLIP, AND SYSTEM FOR PERFORMING SAME

摘要

The present invention is generally directed to a method of measuring stick slip, and a system for performing same. The method includes positioning at least o ne accelerometer in a downhole component of a drill string, the at least one accelerometer being radially offset from a centerline of the downhole component, obtaining acceleration data for the drill string during drilling operations using the at least one accelerometer and determining if the drill string has experienced stick slip based upon mean acceleration values obtained by analyzing the acceleration data obtaine d using the at least one accelerometer.
