针对目标的方位保真局部角度域成像方法
摘要
Abstract
Based on the analysis of the local directional characteristics of seismic waves, we discuss the methodology and applications of azimuth-preserved local angle domain prestack migration for isotropic and anisotropic media. Synthetic and real data examples show the properties and advantages of this seismic imaging approach,and also demonstrate its potential for several applications, such as delineation of the complex geological bodies with multiple angle of view, amplitude variations with incident-angle (AVA) analysis and inversion,azimuthal ani-sotropy analysis,etc. As multiple azimuth or wide azimuth acquisition are more widely used and the high-performance computer technology is quickly developed,we predict that azimuth-preserved local angle domain imaging approach will play an important role for imaging reservoirs and oil and gas prediction.关键词
