可控震源地震采集技术的进展
Keywords: 可控震源,地震数据采集,扫描信号,地面力信号,互相关,反褶积
Abstract:
？可控震源地震数据采集方法可分为常规采集、高效采集及高保真采集三大类。常规采集方法通常是指只采用一组可控震源作业,通过互相关处理获得共炮点道集;高效采集方法是指采用两组或多组可控震源间隔一定时间或同时施工,同样,通过互相关处理获得共炮点道集;高保真采集方法是指采用一台或多台可控震源在彼此间隔一定距离的不同炮点同时振动,采用地面力信号反褶积获得共炮点道集。结合实例分析,对比三类方法特点,可得到两点结论:①可控震源高效采集方法使数据采集作业效率大幅度提高、施工周期明显缩短,进而降低了勘探成本;②可控震源地震数据采集技术的发展方向是高效采集与高保真采集方法相结合,从而实现低成本、高精度及高保真度地震勘探作业。
