摘要
Abstract
AVO analysis and the inversion need to preserve amplitude relative relations when processing seismic data. In conventional processing methods, spreading compensation, stretch distortion and multiple ware can change the relation of amplitude. All above questions are serious, especially for offshore seismic data. This article proposed a new method based on processing data in t -p domain, with do not need spherical spreading compensation , and can improve can correlation of multiple ware, reduce spherical spreading compensation and multiple wave to distort amplitude relative relations, and easily to carry on amplitude stretch correction with robust stretch correction factor, reduce distortion of the frequency and energy which caused by NMO, proposed seismic amplitude preserving processing method for offshore seismic data. Finally actual material processing has confirmed the method rationality and the feasibility through Norwegian offshore seismic data.关键词
