Imaging logging technology is applied widely in casing inspection, casing scale-removing and downhole ashing because of direct expression and more information. The DHV-05 downhole video is designed, which employed wavelet based image-compression, high speed digital modulation transmission, CPLD based demodulation, special mechanism to achieve downhole video image compression, high speed wire data...
Down-hole video captures the borehole images by its mini camera to get real-time information of oil well, it is becoming a hot topic in well logging field. The DHV-05 down-hole video is designed, which employed wavelet based image-compression, high speed digital modulation transmission, CPLD based demodulation, special mechanism to achieve downhole video image compression, high speed wire data transmission,...
