摘要
中原地区地质构造复杂,小断块较为发育,原始地震资料存在着严重的线性干扰和多次波。针对这些原始资料的特点,首先消除线性干扰和多次波的影响,然后利用克希霍夫叠前时间偏移对数据进行处理,并进行了偏移孔径和频率限值的试验,最终处理效果明显,同时交叉地层速度矛盾性问题也得到了有效的解决。
The geological structure is complex in Zhongyuan area, and there is a lot of small block faults in this area. At the same time,raw seismic data are severely dominated by linear noise and multiple. According to the characteristics of raw data in this area, firstly linear noise and multiple are removed, then Kirchhoff pre-stack time migration (KPSTM) is carried out on the data, while aperture and frequency limits are tested. The final processing effect is obvious and velocity picking conflict problem is effectively fixed.
