摘要: 在解决基础静校正后,通常还需要利用剩余静校正方法消除中短波长对成像的影响,但单一的剩余静校正方法并不能彻底解决这一问题。基于地表一致性剩余静校正理论,采用空变多时窗融合剩余静校正方法建立空变的模型道,采用多尺度分频剩余静校正方法消除了频率对模型道的影响,在成像道集上,采用基于共成像点(CIP)道集的时变剩余静校正方法,将这3种剩余静校正方案组成了一套高精度的组合剩余静校正方法,在复杂构造区"两宽一高"地震数据的实际测试结果表明:该方法在兼顾了计算效率的同时,提高了计算精度。该方法能够有效地解决低信噪比、复杂构造区的剩余静校正问题。

关键词: 剩余静校正, 空变, 多时窗, 多尺度, 共成像点

Abstract: The residual static correction method is usually used to eliminate the influence of medium and short wavelength on imaging after solving the basic static correction, but a single residual static correction method cannot completely solve the problem. Based on surface-consistent residual static correction theory, the residual static correction method of space variant multi-time window fusion was used to build space variant model trace. The multi-scale frequency division residual static correction method was used to eliminate the effect of frequency on model trace, and a time-varying residual static correction method based on common imaging point(CIP) gathers was adopted in imaging gathers. The high precision combined residual static correction scheme integrated of the three residual static correction methods was tested in complex structural area with wide azimuth, wide frequency and high density. The results show that the scheme not only considers the calculation efficiency, but also improves the calculation accuracy. The scheme can effectively solve the problem of residual static correction in low SNR and complex structure area with "two widths and one height".

Key words: residual static correction, space variant, multi-time window, multi-scale, common imaging point
