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 positioning the tubular member in the wellbore such that the tubular member is placed under bending stress by a curvature or deviation in the wellbore. The method also includes measuring bend on the tubular member with the strain gauge in at least one plane and determining one or more of the magnitude or orientation of the curvature of the wellbore based on an output of the strain gauge. |

1. A method for determining curvature of a wellbore comprising:
coupling a strain gauge to a tubular member; positioning the tubular member in the wellbore such that the tubular member is placed under bending stress by a curvature or deviation in the wellbore; measuring bend on the tubular member with the strain gauge in at least one plane; and determining one or more of the magnitude or orientation of the curvature of the wellbore based on an output of the strain gauge. |
