在地震资料处理过程中,由于受不同时期野外施工因素差异的影响,经反褶积后的地震子波存在一定的相位差,影响地震资料的拼接效果,而模型子波处理技术是一种估算和减少相位差异的新技术。该技术通过模型试算和实际地震资料的处理,可以消除不同震源、接收仪器引起的地震相位差异,提高地震资料品质与精度。通过对五号桩高精度三维地震资料和桩海大连片地震资料处理的实际应用,消除了不同类型检波器和不同震源导致的地震资料拼接处的相位差异,证明该处理技术非常有效。
During the process of seismic data processing, due to the difference of field construction factors in different periods, the deconvolution seismic wavelet has certain phase difference, which affects the stitching effect of seismic data. The model wavelet processing technique is an estimation And reduce the phase difference of new technologies. Through the model trial calculation and actual seismic data processing, the technique can eliminate the seismic phase differences caused by different seismic sources and receiving instruments and improve the seismic data quality and accuracy. Through the practical application of the high-precision 3D seismic data of No.5 pile and the seismic data processing of the Dalian section of Pile Sea, the phase difference of seismic data mosaic caused by different types of geophones and different seismic sources is eliminated, which proves that the treatment technique is very effective.
