最近几年,地球物理勘探已发展到深水复盖区域的大陆架和大陆斜坡。因此,与海上地震资料有关的混响问题已经成为“长周期多次反射”问题了。巴克斯(1959)在其经典性的论文中已对浅水层复盖区域和接近法线入射的混响多次反射特性进行了描述。他还介绍了压制它们的方法。其后发展了预测反褶积,由于浅水域海上资料的稳定性质,以后预测反褶积就成为压制短周期多次反射的优良方法。随着多次反射周期的增 In recent years, geophysical exploration has evolved to continental shelf and continental slopes in deep-water cover areas. Therefore, the issue of reverberation related to offshore seismic data has become a “long period multiple reflection” problem. Backus (1959) has described the reverberation multiple reflection characteristics of the shallow aquifer coverage area and near-normal incidence in his classic paper. He also introduced ways to suppress them. Since then, predictive deconvolution has been developed. Since the stable nature of offshore data in shallow waters, future deconvolution is an excellent way to suppress multiple short-period reflections. With multiple reflections increasing cycle
