| 摘要 |
A method for determining topography within a wellbore environment comprises locating a probe in a wellbore, directing a beam of light from the probe onto a plurality of positions of a target region within a wellbore environment, detecting light reflected from a plurality of positions of the target region and analysing the detected light to determine a topography of the target region. Light may be directed onto the plurality of positions of the target region at the same time and/or at different times. Such a method may permit features in the wellbore environment to be monitored, or may permit a requirement for maintenance of the wellbore environment to be identified and/or a life-span of the wellbore environment to be predicted. An apparatus for determining topography within a wellbore environment is also disclosed. |
