Characteristics


 ● Perform CT scans on underground wells, generate images and evaluation reports, and automatically assess whether the positions and protection status are reasonable.

 ● Use 3 cameras to observe the downhole environment, obtain three-dimensional stereoscopic data, allowing experts to remotely observe and make judgments. 

 ● Currently, both domestic and international practices use analog television, requiring experts to be on-site; otherwise, downhole environment assessment cannot be conducted.


Basic configuration


 ● 1 set of digital downhole TV controller main unit 

 ● Digital downhole TV monitoring probe 

 ● 1 piece of composite cable, 100 m; built-in tension-bearing steel wire rope, polyurethane sheath, meter mark display scale; 

 ● Food-grade stainless steel probe, with functions of downward observation and 360-degree look around of well conditions; 

 ● 1 piece of portable mobile power supply, 1500 ampere-hours; 

 ● Built-in printer; 

 ● Portable case;

 ● Detailed operation manual.

Application scenarios


● It is used to observe and judge the condition of groundwater monitoring wells. By scanning and shooting along the wellbore with digital downhole television cameras, 

the downhole conditions are displayed through digital processing, so as to accurately determine whether the well wall is damaged or the screen holes are blocked, 

so that timely treatment can be carried out to ensure the 

● authenticity and effectiveness of the groundwater samples collected. It is also a useful tool for judging the maintenance status of monitoring wells.
