BOREHOLE DIGITAL GEOACOUSTIC STATION Russian patent published in 1995 - IPC

FIELD: seismoacoustic prospecting. SUBSTANCE: borehole digital geoacoustic station has source of elastic vibrations connected to generator, the latter being connected to starting circuit which input is coupled to output of land receiver. Land receiver is connected in series to digital-to-analog converter, interface of radiation system and output of synchronization unit. Input of the latter is connected in series to interface of reception system, storage, analog-to-digital converter, unit of keys, demultiplexer, multiplexer and unit of amplifiers. N receivers of elastic vibrations are connected to unit of amplifiers. Unit of keys is linked to program setting unit connected with reception-transmission coupling to interface of reception system. In this case synchronization unit is linked to output of control unit and through unit for information input to input of digital computer. Outputs of the latter are connected to videomultiplication device and registration unit. EFFECT: enhanced operational efficiency. 3 cl, 2 dwg
