摘要： This invention relates in general to measuring depth of well-tools, such as logging tools or the like, in a borehole. Embodiments of the present invention may provide for disposing conducting areas along a wireline that may be used to suspend and move the well-tool in the borehole, where the conducting areas may be disposed along the wireline at predetermined locations. A reader may be located at a reference location and may read when a conducting area passes through the reference location and this information may be used to determine the depth of the well-tool in the borehole. Additionally, this invention provides for combining depth measurements from the conducting areas with measurements from odometer wheels in frictional contact with the wireline and/or time of flight measurements of optical pulses passed along a fiber optic cable coupled with the wireline to accurately and robustly measure the depth of the wireline in the borehole.
