西湖凹陷重点构造的精细处理及其效果分析

东海盆地西湖凹陷的地震资料多次波发育 ,中深层反射能量较弱。国内外多个处理中心对该区资料进行过多次处理 ,但处理结果都不很理想。在分析以往处理流程和处理结果的基础上 ,确定了本次地震资料精细处理以压制多次波为主要目的 ,探索出了一套联合使用Radon变换、预测反褶积和F K变换等方法的处理流程 ,取得了较好效果

REFINED SEISMIC PROCESSING AND ITS RESULT ANALYSIS FOR MAIN STRUCTURES IN XIHU SAG,EAST CHINA SEA BASIN

With developed multiple reflections and weak reflections of the middle?_deep horizons, the seismic data in Xihu sag, East China Sea basin, have been processed for many times by several domestic and foreign seismic processing centers, but the results weren't perfect. Based on analyses of previous processing flows and results, it is decided that this refined seismic processing will focus on suppressing multiple reflections. Thus, a processing flow in combination with Radon transform, predictive deconvolution and F?K transform is developed and better processing results have been achieved.
