【摘要】 文章简述了海洋地震勘探系统的组成,介绍了海洋地震勘探震源的工作原理和代表产品、型号,分析了各类震源的频谱特性和应用范围。枪震源子波频率低、穿透深度大,主要用于深层地震勘探;电火花震源、BOOMER震源及剖面仪震源子波频率渐高、穿透深度渐小,主要用于浅层高分辨率地震勘探。为了发挥不同震源的优点,可以将不同种类震源组合使用,即“双震源三缆接收技术”。更多还原

【Abstract】 Composition of the marine seismic prospecting system is recounted. The operational principles and characteristics and applications of four types of seismic sources are introduced and studied. The analysis results demonstrate that gun is fit for deep seismic prospecting because of its low frequency, and sparker, BOOMER and profiler are fit for shallow seismic prospecting because of their higher frequency. To develop their strong suit of seismic sources, using two types of them in one exploration survey is a good idea. That is the technique of two seismic sources and three cables.更多还原
