METHOD AND APPARATUS FOR CONTINUOUS WELLBORE CURVATURE ORIENTATION AND AMPLITUDE MEASUREMENT USING DRILL STRING BENDING

摘要

A method includes coupling a strain gauge to a tubular member, and positioningthe tubularmember in the wellbore such that the tubular member is placed under bendingstress by acurvature or deviation in the wellbore. The method also includes measuringbend on thetubular member with the strain gauge in ate least one plane and determiningone or more ofthe magnitude or orientation of the curvature of the wellbore based on anoutput of the straingauge.
