ABSTRACT:
The invention relates to seismic sources in which a shock wave is produced in a liquid mass by the implosion of a volume of vapor, particularly water vapor. According to the invention, the vapor to be imploded is formed inside a closed, flexible enclosure, surrounding an injection head, fitted with a vapor opening 103 capable of releasing vapor at 5 bars and 170.degree. C., controlled by an electromagnetic valve. Liquid nuclei are advantageously introduced into this vapor by means of a pipe for cold water which is under pressure and under the control of an electromagnetic valve, this water arriving in the cavity in order to exit through spray openings. These nuclei produce a vigorous drop in pressure inside the vapor, and hence an implosion and a shock wave, after which a pipe allows the condensate to be recovered. The invention is of use notably as a seismic marine source.
