1.5维逆散射级数法消除海上地震勘探资料中的鬼波
Marine Seismic Data Deghosting With 1.5D Inverse Scattering Series Method
摘要
Abstract
In order to solve the problems such as large computation and high requirement of geometry in the traditional 2D ISS (inverse scattering series) method, the 1.5D ISS deghosting method is proposed after dimen-sionality reduction from 2D ISS method. The examples of data study show that the 1.5D method can save lots of calculation and also degrade the requirement of geometry. 1.5D ISS method does not need any subsurface infor-mation and wavelet estimation, and it is suitable for different kinds of complex structure and low signal to noise ratio seismic data. Besides, the 1.5D ISS method can remove the ghosts from marine seismic data effectively and enhance resolution; simultaneously it will expand the frequency band and compensate the null frequencies energy.关键词
