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 power, displacement of such elements (30) is enlarged by the slotted housing (12) to 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 self-contained marine vehicle.

一种用于在海洋地球物理作业中产生地震源能量的地震方法和系统。 开槽壳体(12)可通过致动压电元件而移动,以产生高功率,低频地震源信号。 当压电元件(30)被电力激活时,这些元件(30)的位移被开槽壳体(12)扩大,从而在水中产生压力脉冲。 本发明允许具有足够功率和低频率的单源压力脉冲产生。 壳体(12)可以被地震船拖动,或者可以集成到独立的船用车辆中。
