Methods for Estimating Wellbore Gauge and Dogleg Severity

摘要

Methods for measuring wellbore gauge and dogleg severity are disclosed. The methods include deploying a downhole tool in a subterranean wellbore. The downhole tool includes first and second axially spaced stabilizers deployed on at least one tool body section coupled to a universal joint. The method for measuring wellbore gauge further includes measuring first and second axial directions of the tool body section when the universal joint is tilted in corresponding first and second cross-axial directions and processing the first and second measured axial directions to estimate the wellbore gauge. The method for measuring dogleg severity further includes measuring first and second tilt angles of the universal joint when the universal joint is tilted in corresponding first and second cross-axial directions and then processing the first and second measured tilt angles to estimate the dogleg severity.
