摘要
本文的方案设计中将视频转换、视频压缩/解压、数字信号高速远距离传输及字符叠加技术应用到成像测井中。试验结果证明通过3000m的传输电缆,该系统在1Mbps的传输速率下能获清晰的井下实时动态图像,并能将与测井相关信息叠加到图像中。对提高油田测井的准确性、实时性、有效性提供了很大帮助。
The technology of video conversion and video compression/decompression, and the technology of high-speed long-distance transmission of digital signal and characters superimposition are all used in the down-hole vedio image system in this plan. The test result proves that through the 3000m cable, it can get real-time dynamic down-hole image clearly at the rate of 1Mbps and the relevant information, and superimpose the information in the video. It improves the accuracy, realtime and validity of logging greatly.
