摘要
Abstract
Wide azimuth data acquisition leads a few problems in data processing,such as velocity variation with azimuth, azimuth-dependence travel time correction, azimuth-dependence anisotropy. For wide azimuth data (not full azimuth data) ,it is ver-y crucial to form reasonable azimuth sectors which are favorable for processing and interpretation from real data. In this paper we propose a set of solutions including azimuth sector forming, azimuth accurate stack velocity estimation; azimuth-dependence travel time correction and azimuth ani-sotropic pre-stack migration. Improved results have been achieved with applications of these techniques, and show that our approaches are feasible.关键词
