System and method for coupling an overpressure wave to a target media

摘要

An improved seismic exploration system and method involves an overpressure wave generator for generating an overpressure wave and a coupling component for converting a pressure of said generated overpressure wave into a force that produces a conducted acoustic wave in a target media. The coupling component includes a coupling chamber, a push plate assembly including a top plate, piston rod, and an earth plate, a movement constraining vessel including a stabilizing component for constraining movement of the push plate assembly and a sealing component for substantially sealing the coupling component, and a stop component for preventing the movement constraining vessel from striking the earth plate.

1. A seismic exploration system, comprising:
an overpressure wave generator for generating an overpressure wave; and a coupling component for converting a pressure of said overpressure wave into a force that produces a conducted acoustic wave in a target media, said coupling component comprising:
a coupling chamber for receiving said overpressure wave from said overpressure wave generator;a push plate assembly, comprising:
a top plate;a piston rod; andan earth plate;a movement constraining vessel for constraining movement of said push plate assembly resulting from said coupling chamber receiving said overpressure wave, said movement constraining vessel comprising;
a stabilizing component for constraining movement of said piston rod to only movement that is substantially parallel to the sides of the coupling chamber and the movement constraining vessel; anda sealing component for substantially sealing said coupling component during generation of said overpressure wave; anda stop component for preventing said movement constraining vessel from striking said earth plate.
