【摘要】 随着地震资料处理技术的不断发展,对苏北盆地海相中古生界地层构造特征研究有了进一步的深入,使以往采集的该区地震资料能在其研究中发挥更大的作用,提高资料的处理精度显得非常重要。以黄桥地区为例,由于受当时技术因素所限,获得的低信噪比、低分辨率处理成果已不能满足当前研究的需要。结合该地区的资料特点,在解决了低信噪比资料的静校正、干扰波处理、振幅一致性校正的基础上,重点进行了反褶积方法测试。处理结果表明,多时窗地表一致性反褶积方法不仅能改善该区资料的信噪比,还能提高其分辨率。更多还原

【Abstract】 With the progress of seismic data processing technology,the studies on the stratigraphic properties in marine middle Paleozoic Erathem in north Jiangsu were deepened,and the seismic data collected in the area previously would play an important role in the further study in light of improving the processing accuracy of the data.Citing Huangqiao as an example,restricted by the technology,the processed results on low signal-to-noise and low resolution obtained then could not satisfy the present requirement.In combination with the data characteristics of the study area,and based on the static correction of low signal-to-noise data,treatment of disturbing wave and correction of amplitude consistency,the author focused on the testing of deconvolution.The results showed that the grated surface consistency deconvolution could not only improve the signal-to-noise but also improve the resolution of the data in the area.更多还原
