摘要
针对高分辨采集的地震资料 ,采用了高分辨地震资料处理的各种技术 :地震资料叠前提高信噪比处理、提高反射信号主频和展宽有效信号频带、分频处理方法、优化迭代叠加方法、信号方向约束预测去噪方法、三维FXY域预测道内插方法等 ,并讨论了叠后提高横向分辨率问题 ,在实际资料处理中取得了较好的效果。
This paper discusses various high resolution seismic data processing techniques suitable for data acquired with high resolution means. These techniques include prestack S/N ratio enhancement, heightening of the dominant frequency of reflected signals and spreading of the frequency band of significant signals, frequency divided processing, iterated optimal stack, signal direction constrained noise elimination, as well as predicted trace interpolation in 3-D FXY domain. Issues of enhancement of lateral resolution after stacking are also discussed. Desired results have been reached by the application of these methods to real seismic data.
