摘要

三维地震勘探是一种面积勘探方法,观测系统形式很多,常用的线束型三维观测系统,由于其排列片狭长,存在方位角分布不均匀的弊端。宽方位观测系统采集技术较之常规束状采集技术在各个方位角上的炮检距和覆盖次数分布均匀、合理。将宽方位三维地震勘探采集技术应用于上海庙矿区,得到了品质较好的地震资料。取得了很好的技术效果和显著的经济效益。
3D seismic prospecting is a kind of areal survey, There are many types of 3D layout.Ordinary field 3D layout which has been often used in 3D seismic has a weakness of non-uniform azimuth in bins because its patch appears narrow and long rectangle.There method posse more reasonable on the distribution of distance between shot and geophone and on the distribution of fold in every azimuth, as compared with the regular swath geometry. By 3D seismic exploration aimed at wide-azimuth processing and analyzing of the seismic data produced, it is proved that it have get a better quality of seismic data in Shanghaimiao mine.And have gained a very good technical results and remarkable economic profits.
