| 摘 要： | 通过对南海某工区不同采集参数采集的地震数据的分析,就海上拖缆地震勘探中震源及电缆的沉放深度对采集数据质量影响进行讨论,得出如下结果:震源沉放越浅,子波频带变宽,高频效果越好;电缆沉放深度越浅,频带越宽,分辨率越高,但受风浪影响的噪声比较大。这为地震资料采集和后续的地震资料处理提供了良好的依据。

| Abstract: | Based on an analysis of seismic data collected with different acquisition parameters in a work area of the South China Sea,this paper deals with the impact of the sinking depths of seismic source and cable on the quality of collected data in marine tow seismic exploration.The results are as follows: the shallower the seismic source sinking depth,the better the high frequency effect with the broadening wavelet frequency band;the shallower the cable sinking depth,the broader the frequency band,and the higher the resolution ratio,but with rather high noise resulting from stormy waves.The results obtained provide good basis for seismic data acquisition and subsequent seismic data processing. |
