准噶尔盆地西缘山前带浅层高分辨率地震采集方法

Techniques for high resolution seismic acquisition of the shallow stratum in the piedmont zone on the western margin of Junggar Basin

对准噶尔西缘山前带超浅层进行了地震采集方法研究。针对山前带超浅目的层的勘探难点,采用提高分辨率地震采集方法,进行具有针对性的方法设计,最大限度地改善激发、接收效果,提高资料的分辨率和信噪比;最终取得了复杂山前带浅层高分辨率地震勘探采集方法,获得了较高品质的地震资料。

This paper deals with the techniques for seismic acquisition of the shallow stratum in the piedmont zone on the western margirr of Junggar Basin. in order to overcome the difficulties in prospecting the shallow stratum, the high resolution seismic acquisition techniques are adopted and designed so that the effect of exploding and receiving can be improved to a large extent and the resolution and signal to noise（s/n） ratio of data raised. As a result,higher-quality seismic data are obtained.
