井下摄像技术在套损井检测中的应用

Application of Downhole Imaging Technique in In-spection of Wells with A Broken Casing

介绍了一种用于井下套管损坏情况检测的井下摄像系统,它由井下摄像机和地面图像处理系统组成,可以实时观察井下套管弯曲、变形、缩径、破裂等情况,为查清套损原因及实施套修提供了准确、可靠的依据。

A downhole imaging system,with a downhole cam-era and a surface image processing system,is introduced for inspecting casing damage.It can perform real time inspection of casing bending,distortion,constriction and breaking,thus provide accurate and reliable data for checking the causes of casing damage and repairing the damaged casing.
