Asymmetrical lateral-force seismic source transducer

摘要: A spark discharge acoustic pulse transducer for borehole operation provides an insulating ceramic barrier which contains a small cross-section aperture separating two bodies of electrolyte through the zones liquid make contact. An electrical arc is caused to occur produce transient pressure and associated coupled geologic formation at wall. The specific shape geometry channel in being exponentially shaped means controlling waveform frequency spectrum pulse. has elastic outer housing inner with hydraulic fluid between housings. may be increased expand against borehold prior discharge. also provided system venting gas produced as result designed asymmetrical forces on wall azimuthal plane about chamber axis.
