ACOUSTIC ENERGY SOURCE AND METHOD FOR GENERATING A PRESSURE PULSE IN WATER, AND SEISMIC MARINE SOURCE

摘要

P The invention relates to a marine seismic source for generating acoustic energy. It comprises a housing (18) having a continuous external perimeter and capable of displacing water. The outer surface (20) of the housing (18) comprises a concave part (22) and a convex part (24) connected by two inflection points (26 and 28). An actuator (30) can be activated to move the surface of the housing and vary the volume within it. The resulting pressure pulse provides acoustic energy usable in marine seismics. Area of application: evaluation of underground geological formations, etc. /P
