【摘要】 针对泌阳凹陷地震资料的特点及目前实际生产中存在的问题,在叠前噪声压制方面提出了一些具体做法。通过对面波、声波的压制,线性干扰的自动识别和压制,单频干扰的压制,野值脉冲干扰的去除及随机干扰的压制,使资料信噪比有较大提高,从而在整体上提高了地震资料处理的精度。并提出不同地区资料应采用不同的方法,进行有针对性的处理,才能有效压制噪声。更多还原

【Abstract】 In view of seismic data characteristics and current prob-lems in actual production, some specific practices on pres-tack noise suppression have been introduced in this paper.Through suppression of surface wave and acoustic wave, automatic identification and suppression of linear interference,suppression of single-frequency interference, elimination ofburst noise and suppression of random interference, the signal to noise ratio has been greatly improved, resulting in anenhanced accuracy of seismic data processing as a whole. Besides that, the paper also points out different methodsshould be used in different area to carry out specific processing. Only by doing so, noise suppression could be effectivelyrealized.更多还原
