摘要: 南海东北部陆坡深水区地质构造、地球物理特性复杂,进行地震资料采集时,如何获得中生界的高品质地震资料至关重要,而选择合适的地震采集参数是关键。7、10和12 m电缆沉放深度试验表明不论从频率分析,还是从子波特征、子波能量各方面均可发现7 m的沉放深度较优。

Abstract: Characteristics of geological structure and geophysical field in northeast continental slope of the South China Sea are complex.When seismic data are collected, it is important how to get high quality seismic data of Mesozoic,and the key is to choose appropriate parameters of seismic data acquisition. The test of cable sinking in 7,10 and 12 m depth indicated the seismic data acquisition with cable sinking in 7m was excellent in subwave figure and frequency scanning effect.
