摘要
Process for preparing vertical seismic profiles(VSP) of the underground interested by a boredrilling, by using, as the seismic source, thevibrations generated by the drilling bit, by carryingout a cross-correlation between the bit signal and thesignals collected by seismic geophone lines, in whichthe bit signal is processed by arranging a pluralityof several types of detectors on the bore drillingfacility and thus recording a plurality of traces: inthem the signal/noise components have differentcharacteristics and can be separated by means of theintroduction of filter functions by operating on theirFourier Transforms or on the basis of their statisticdistribution.
