High degree of visualization
Downhole television can intuitively present the actual situation underground. Through clear image display, whether it is the internal state of the casing in the oil well, the formation structure, or the tunnel wall in the mine, the location of the aquifer, etc., it can be seen at a glance. For example, in oil exploration, the corrosion position and degree of the casing, as well as the porosity of the oil layer, can be clearly seen, just like installing a pair of "eyes" underground, allowing ground personnel to observe the details of the underground in real time. This visualization feature is difficult to match with some other traditional detection methods.
Non-contact detection
It mainly relies on optical imaging and signal transmission technology to detect without direct contact with the object being measured underground. This enables downhole television to effectively avoid equipment damage or interference with the object being measured due to contact in a complex underground environment. Taking the observation of rock cracks underground as an example, the downhole television can shoot at a certain distance without direct contact with the rock like some physical detection tools, reducing the risk of equipment damage, while also ensuring that the original state of the rock is not damaged, which is more conducive to accurate observation.
Flexible and variable detection range
The detection range can be flexibly adjusted according to the focal length, field of view of the camera, and the lifting, rotation and other operations of the equipment. If you need to observe the details of a local area in the well, such as a tiny crack on the casing, you can zoom in and reduce the field of view for high-precision observation; and when you want to understand the general situation of the entire wellbore, you can zoom out and increase the field of view to quickly scan the entire wellbore space. This flexible and variable detection range allows the downhole TV to obtain appropriate downhole information according to different detection purposes and requirements.
Adaptable to a variety of downhole environments
Downhole TV equipment generally has good sealing and pressure resistance, and can work in harsh downhole environments such as humidity, corrosive liquids, high temperature, and high pressure. Its outer shell is usually made of sturdy metal materials, such as stainless steel, and the well-sealed design can prevent water and other corrosive substances from entering the interior of the equipment. At the same time, the internal electronic components and optical components are also specially treated to withstand the pressure changes in the well. For example, in the detection of deep-sea oil wells, downhole TV can work normally in an environment of high pressure, low temperature and strong seawater corrosion, and effectively monitor the downhole situation.
Strong real-time information acquisition
Downhole television can transmit underground images to the ground control center in real time. Operators can operate the equipment on the ground while observing the dynamic situation underground. When an emergency occurs in a mine, such as water gushing, landslides, etc., the underground television can be quickly lowered to the relevant location underground to provide real-time feedback on the actual situation of the underground site, provide timely and accurate information for emergency rescue, and help rescuers better formulate rescue strategies.
Data can be recorded and replayed
Downhole television systems are usually equipped with data storage functions, which can record images and related data during underground detection. These recorded data can facilitate subsequent research and analysis, and also help to track and compare underground conditions for a long time. For example, in the life cycle management of oil wells, the corrosion process of the casing and the dynamic changes of the oil layer can be observed by replaying downhole television records from different periods, providing data support for the maintenance and transformation of oil wells.
