摘要
以舞阳凹陷原始地震资料为基础，分析研究出一套适合该区特点的高分辨率地震资料处理方法。主要应用了叠前地震资料噪声压制，地表一致性处理，压缩于波展宽有效波频谱，高精度同相叠加，叠后f－x域信号方向约束去噪等处理技术，取得了很好的处理及地质效果，最终处理结果有较好的波组特征，断面清楚，断点可靠，在地震解释构造图上，断层的分辨率增高，断裂展布更符合地质规律。
Bascd on the initial seismic data of Wuyangdepression, a set of methods of high resolution seismicprocessing are studied including noise suppression ofpre - stack seismic data, surface - consistent processing,wavelet compression and frequency spectrum expansion ofeffective wave, highly accurate in - phase stack, andpost - stack f- x domain signal direction restraint noiseelimination. Processing achieves reflected wave characterof high quality, clear and reliable fault planes, more faultsin seismic interpretation map and more reasonable andregular fault strike distribution.
