摘要
影响山地资料成像的原因是多方面的,其中由于复杂地表特征带来的噪声发育问题是重要原因之一。采用宽线横向大基距组合检波方式采集,可以大幅度压制侧面及各种地表因素带来的散射噪声,有效的提高原始资料的信噪比。在库车山地采集中,通过不断优化应用宽线大组合提高了资料品质,取得了较好的效果。
The causes affecting the mountain seismic data image are various.One of the most important causes is the noise development caused by complex surface characteristics.The scattering noise caused by various flank and surface factors can be suppressed by using detection method of broadened line and lateral long distance geophone array in seismic data acquisition,which effectively improves the signal-to-noise ratio of original data.During the mountain seismic acquisition in Kucha,data quality is improved through optimized application of broadened line plus large geophone array,and good effect is achieved.
