海洋宽频高精度地震处理技术及其深层岩性勘探实践
Broadband and high-precision sesmic processing technology and its application on offshore deep lithology exploration
摘要
Abstract
Broadband and high-precision processing of offshore horizontal cable 3D data is receiving increasing attention in the exploration of lithological oil and gas reservoirs recently.However,specialized analysis and dis-cussion are lacking.The broadband high-precision processing technology of 3D data of offshore horizontal cables was systematically summarized,and the procedures of broadband high-precision processing and key technologies of horizontal cables in shallow water area were established,including mainly the deghosting in horizontal cables,pre-stack integrated multi-domain denoising,shallow-water multi-wave combinational suppression,and target-based fine-velocity modeling and fine-migration imaging,etc.By applying real data on the western slope of Xihu Sag,the broadband,amplitude-preserving and high-precision seismic results with improved resolution were ob-tained.The reservoir inversion and geological evaluation carried out by the results are in good agreement with new drillings,from which the geological viewpoint obtained is more reasonable.关键词
