| Abstract: | The influence of the tool eccentricity in oil well casing on the televiewer image is investigated. A correcting approach based on the computing model is proposed. The processing result shows that the approach can eliminate the vertical black strips on the image caused by the tool eccentricity, and improve reasonably the image quality. By contrast enhancing, the details of the image can be more clarifier. |
