Introduction to underground TV

The downhole TV imaging system is a relatively new logging technology that can visually monitor the technical status of downhole tubing or casing. Using digital image processing technology, the downhole TV image is digitally processed, image segmented and edge tracked; and using

The imaging principle derives the geometric size of the real object in the TV image, achieving the purpose of quantitative interpretation of underground TV. Practical applications have shown that the interpretation results of this quantitative method are accurate and reliable, which is a further improvement of underground TV logging technology.

Complementary with downhole imaging, it plays a decisive role in well logging.

In actual observation, the quality of the detector determines the quality of the TV imaging.
