SLOTTED CYLINDER MARINE SEISMIC METHOD AND SOURCE |
摘要 |
A seismic method and system for generating seismic source energy in marine geophysical operations. A slotted housing (12) is moveable by the actuation of piezoelectric elements to generate high power, low frequency seismic source signals. When the piezoelectric elements (30) are activated by electric powe r, displacement of such elements (30) is enlarged by the slotted housing (12) t o generate a pressure pulse in the water. The invention permits single source pressure pulse generation having sufficient power and low frequency. The housing (12) can be towed by a seismic vessel or can be integrated into a se lf- contained marine vehicle.
