The process of auto-predicting and eliminating pulse noise in seismic data can be conducted on the basis of frenquency filter+dynamic balance in single channel record. The long time window dynamic balance conducted before pulse noise elimination benefits the appearance of pulsenoise. The subsequent short time window dynamic balance + frenquency filter eliminate the high frequency "burr" interference and record the energy balance of sub-shallow-deep beds. The prediction and elimination of pulse noise do not need sliding time window, i. e,each processing time window length is equal to the channel length. So this algorithm is simple and efficient. The method described here can also be used in auto-prediction and attenuation of extremely big amplitude on iterated profiles, and can effectively reduce "arc curve" on offset profiles resulting from point pulse records.

自动检测和抑制地震记录中猝发噪声的处理过程可在单道记录上频率滤波+动平衡的基础上进行。猝发噪声抑制前所做的长时窗动平衡,有利于猝发噪声的“显露”,其后的短时窗动平衡+频率滤波过程以消除高频“毛刺”干扰及记录中浅深层能量的均衡.猝发噪声的检测与衰减不需滑动时窗进行.即每次处理的时窗长度等于道长,因而该算法简单、高效.文中所述方法也可用于迭后剖面上异常大振幅的自动检测与衰减,并能有效地减少由于点脉冲记录引起的偏移剖面上的“画弧”现象.

本文依据反散射理论,利用Born近似将非线性波动算子线性化,通过格林函数建立散射波场与散射势能的关系;再由WKBJ近似给出随深度变化的格林函数的解析表达式,得到散射波场的解析解;并针对大入射角时振幅的畸变,提出一个用于振幅修正的因子。该方法在ω-P域内实现,可以解决把地震资料作为线震源响应所引起的深层能量太弱的问题

The problem of multiple reflection in Yili area is always the main interference to prevent technicians from getting seismic reflections in deep area and making clear the geological conditions of petroleum reservation. The key to get breakthrough in this area's exploration is to decrease multiples effectively. In this paper, the authors select some proper methods to make clear the differences between primary and multiples by means of analyzing the characteristics of multiples in detail. In the process of multiples decreasing, the anthors take several effective techniques such as deconvolution, FK filtering, τ-P transformation, time variable internal mute and etc. In the process of energy compensation in deep area, automatic residual static and random noise decreasing are used repeatedly. By means of these methods, not only the energy of primary reflection was enhanced, but also they have better continuity and can be traced easily. The result is true and reliable.

伊犁地区多次波问题一直是限制该区石油地质研究及获得深层地震反射资料的主要干扰,有效地压制多次波是该区油气勘探获得突破的关键,本文通过对伊犁地区多次波特征的分析,选取合理的识别方法分辨一次波和多次波,在衰减多次波过程中,综合使用了反褶积、F-K滤波、τ-P变换和时变下切除等手段,在补偿深层能量处理中,采用多次自动剩余静校正迭代和随机噪音衰减等方法。利用这些方法所处理的地震剖面多次波得到有效衰减,一次波反射能量加强,真实可信,并且有一定的连续可追踪性。
