Switching system for the acquisition of seismic data
This patent describes a seismic recording system. It comprises: a multichannel magnetic tape recorder; a cable comprising a plurality of signal conductors, each of the signal conductors being connected to a different channel of the recorder, the cable having a plurality of takeouts located at uniformly spaced distances along the length of the cable and each of the takeouts being connected to a different signal conductor; a plurality of conduits, each of which has an end operably connected to a different one of the takeouts; a plurality of switch means dispersed along the length of each of the conduits and operably connected thereto; a plurality of detector conduits, each of which has an end connected to a different one of the switch means; an array of seismic detectors located along the length of each of the detector conduits and operably connected thereto; and control means for transmitting a digital signal through selected signal conductors of the cable to the switch means for electrically interconnecting selected detector conduits and arrays of seismic detectors with the multichannel recorder.
