摘要
针对玛湖斜坡区三块三维地震资料和赛汉塔拉凹陷二块三维地震资料连片处理中的特点,结合地质任务和处理目标要求,提出了地震数据连片处理中的地震子波处理的方法.该方法主要体现了两次反褶积,一次是采用地表一致性反褶积,将不同震源的频带拓宽到一个标准上;再一次采用相位校正反褶积,将不同震源的数据校正到相同相位上.为了保证提取的相位校正反褶积算子稳定,采用叠后地震道提取(主要考虑到叠后地震道信噪比高,算子稳定性强),然后将该算子应用到叠前地震道,进行相位校正.
Facing data characteristics of seismic processing to merge 3 D seismic data from 3 area in Zhun Ge er Basin and 2 area in San Han-tala Depression , according to purpose of seismic processing and geology , seismic wavelet processing method to merge 3-D seismic data from multi-area is put forward in this paper . It is included that two deconvolution in the method： surface consistent deeonvolution to widen frequency band consistently; phase correction deconvolution to obtain consistent phase from different vibratory source. In order to gain steady operator of phase correc tion deconvolution from poststack seismic trace（signal to noise ratio in poststack seismic trace is higher in prestack seismic trace）, phase correction deconvolution will be used to prestack seismic trace for phase correction.
