摘　　要：井下电视成像系统是一项较新的测井技术 ,可以直观地监测井下油管或套管的技术状况 .利用数字图像处理技术 ,对井下电视图像进行了数字化处理、图像分割和边缘跟踪 ;并利用成像原理得出了电视图像中实物的几何尺寸 ,达到了井下电视的定量解释目的 .通过实际应用表明 ,该定量方法解释结果准确可靠 。Downhole television image system is a kind of newer well logging technology. The technological condition of oil pipe or casing pipe can be directly viewed through it. In this paper, the downhole television image is digitized and cut apart by using the digital image processing technology. The edges in the image are tracked. Then the geometry size of the object in the television image is obtained according to the imaging principle. The quantitative interpretation of the downhole television image is achieved. The practical application shows that the result of the quantitative interpretation is accurate and reliable. The method further perfects downhole television logging technology.
