Abstract: A method for processing fused “underground+ground” data in deep formation exploration includes: collecting underground multi-source data by an underground intelligent probing rod, preprocessing the multi-source data to obtain an original digital signal, storing the original digital signal in an underground memory, obtaining continuous depth data by a ground device; performing high-bitrate and low-bitrate compression on the original digital signal, and modulating compressed signals; driving modulated signals by power, so the modulated signal is transmitted in a drilling stem with cable in a form of a power line carrier and then output, or first transmitted in a first section of the drilling stem with cable, re-collected in a short drill pipe with repeater, re-emitted to a second section of the drilling stem with cable, and then output; when a transmission line is disconnected, synchronizing and fusing data; and finally using fused data and the data output by the transmission line as final output data.
