摘要
通过系统研究单道地震数据采集技术方法,结合项目实际应用效果和海上试验结果,从震源的选择、环境背景噪声特点、接收水听器实际效果、单道地震采集系统方法改进等方面进行了分析研究。总结了一套可行的单道地震调查施工技术方法,采用一发双收双通道地震采集系统,可达到提高单道地震剖面分辨率和获得高信噪比资料的目的。
The data acquisition technique for single-channel seismic survey was systematicly reviewed in this paper in order to improve the resolution of single-channel seismic profiles and enhance the sig- nal/noise ratio. Based on our experience in practice and sea testing under various boundary conditions, such as different sources, different regional background of noise characteristics and different receiving hydrophones, we proposed a feasible data acquisition system in this paper for single-channel seismic survey. High resolution and high signal/noise ratio may be achieved through the new system.
