The invention discloses geophysical exploration cable which comprises a cable core and an outer wrapping layer wrapping the cable core. The cable includes multi-strand parallel inner core cable yarns, and multi-beam geophysical cable yarns are arranged on the outer wrapping layer at intervals along the lengthwise direction of the geophysical exploration cable. The geophysical exploration cable has the advantages that the parallel inner core cable yarns are adopted by the cable core and are made from ultra-high molecular weight polyethylene fiber, and the geophysical exploration cable is less prone to bending and twisting; the cable strands are extracted from the outer wrapping layer to serve as the geophysical exploration cable yarns, the geophysical exploration cable yarns are used for fixing an observation apparatus, and effects that the geophysical exploration cable is less prone to bending and twisting and the observation apparatus is fixedly conveniently to have ocean explored are achieved.
