【摘要】 地震勘探装备和技术的飞速发展为高密度单点地震采集技术的应用提供了可能。通过对比分析贵州中部某山区盒子波资料、单点采集与组合接收野外试验资料以及叠加剖面,探讨了单点采集与组合接收的差异性。研究表明,组合接收会造成地震波主频降低,进而会影响叠加剖面的分辨率;单点采集有利于保护有效波的频率成分,但地震资料的信噪比较低。更多还原

【Abstract】 The rapid development of seismic exploration equipment and technology made it possible for using high-density single point seismic acquisition technology.The differences of single point acquisi-tion and array receiving were explored by using comparative analysis of Box wave data,single point acquisition,array receiving field test data and stack section in the middle mountainous area of Guizhou Province.It shows that the array receiving would reduce the domain frequency of seismic wave,and then impacts the resolution of the stack section;single point acquisition keeps the frequen-cy components of the effective seismic waves,but the signal-to-noise ratio of seismic data was relatively low.更多还原
