Air-driven mechanic acoustic seismic source for shallow high resolution marine geophysical profiling

本文介绍了气动机械声波水域高分辨率浅层地震勘探连续冲击震源的研制技术背景,分析了新型气动机械声波水域震源的震源子波特性,通过与国内外常用的水域地震震源的分析对比,新型震源具有能量适中,震源子波余震小、衰减快、频带较宽、穿透深度较大的特性,工程实例说明了新型震源在水域岩土工程勘探中具有良好效果。

The paper introduces the technical background of the invention of air-driven mechanic acoustic seismic source for shallow high resolution marine geophysical profiling. The source wavelet is analyzed with the characteristics of medium energy, low aftershock, fast attenuaton, wide frequency band and deep penetration, in comparison with the other popular marine seismic sources. A real marine project shows that the new seismic source device is very suitable and effective to acquire high quality marine geophysical profiling.
