摘要
针对涠11地区地层速度变化大,尤其是纵向上变化强烈,以及地震反射波交叉严重等特点,摸索出了一种组合式三维叠前加叠后时间偏移技术,即F-K三维叠前时间偏移与维数分裂法叠后时间偏移组合技术。应用该项组合偏移技术,可缩短地震资料的处理周期,提高处理效率,并较大程度地改善偏移成像的质量。
In W11 area, the seismic interval veloci- ty changes greatly, especially vertically, and the reflected waves intersect each other seriously. In order to solve these problems, a new combination technique of F-K 3D pre-stack time migration and dimension split post-stack time migration has been developed. By applying this technique, we can decrease the time of seismic data processing, improved the processing efficiency and more significantly improve the quality of migration imaging.
