In the production process of coalbed methane well, due to casing damage, falling objects, sticking and other reasons, the continuous production is affected. In order to accurately identify the complex conditions of the gas well, the underground real-time camera technology can be used to diagnose the complex conditions of the underground, and provide a reliable operational basis for the next step of the overhaul construction measures. Through field application, the downhole camera technology can provide an accurate real-time picture of the gas wellbore, clearly capture the complex situation in the casing from the wellhead to the bottom of the well. It is of great guiding significance to analysis the causes of downhole faults and develop accurate repair measures.
