Recently, China National Offshore Oil Corporation's "Deep Sea Guide" geological trajectory rotary steering drilling system has established a "well-ground-base" full-link high-speed communication channel, with cumulative transmission curves exceeding50 thousand, and total data volume surpassing500G, marking a breakthrough in China's oil and gas directional drilling technology. Dubbed the"Deep Earth Guidance" technology, it enables precise drilling by"targeting deep reservoirs and drilling along reservoir boundaries". Through digitally constructed real-time data transmission links and the innovative use of fluid pressure wave transmission technology, it achieved China's first ultra-long-distance data transmission over9000 kilometers to Uganda, successfully pinpointing deep reservoirs. Currently, the "Deep Sea Guide" system has been widely deployed across China's offshore and onshore oil fields, and promoted to "Belt and Road" partner countries like Indonesia and Iraq.
