VideoLog Downhole TV Client Software Development

VideoLog Downhole TV is the only downhole TV equipment in China that can transmit color full frame rate logging video on 7000 m traditional armored logging cable.The VideoLog downhole TV uses the camera sensor to collect the downhole video image.The captured video image is transmitted back to the ground control system by the well logging high-speed remote transmission technology.The video image transmitted back to the ground needs to be processed in real time and superimposed on the video image.Character information,while PTZ control.Therefore,a client software is needed to process the logging video image in real time,superimpose the logging character information and control the camera orientation,lens focal length,and lighting.This can greatly assist the logging personnel in real-time analysis of downhole conditions,record important logging information,facilitate the study of repair well solutions and accurately evaluate the repair well conditions.According to the requirements of VideoLog downhole TV logging equipment,Logging video is transmitted using the RTSP streaming protocol.the returned video is H.264 decoded and played,and the character overlayer and OpenCV technology are used to dynamically superimpose characters on the video image,and the camera communication is controlled by a custom communication control protocol.,focal length.Using the Microsoft Visual Studio 2013 development tools,the VideoLog downhole TV client software was developed using the C++programming language.The software system has been developed.The VideoLog downhole TV client software has been tested in the laboratory environment to ensure all functions are normal.Now it has served in the oil gas well logging of major oil fields,and has recorded more than 30 wells and found more than 10 difficult wells.repairing wells in major oil fields,and the risk of evading losses is several hundred million yuan.In the actual oilfield logging process,the client software has stable performance and can play high-quality logging videos in real time.The characters in the video are beautifully labeled and the pan/tilt control is smooth.it has strong practical application value.
