| 摘 要： | 三维地震数据的同一共中心点道集是由不同方位角的地震道组成的。当地下地层倾斜时，共中心点道集的反射同相轴就存在方位角时差。本文根据方位角时差校正（ＡＭＯ）的基本原理，从ｆ－ｋ域的正、逆ＤＭＯ出发，通过稳相法得到积分法ＡＭＯ脉冲响应的时间、振幅因子公式。把ＡＭＯ应用于一束实际三维地震数据处理，经ＡＭＯ处理后的剖面绕射波和断面反射波得到了加强，其效果是令人满意的。

| Abstract: | The same CMP trace gather of 3 D seismic data consists of different traces with different azimuths. When there is a dip interface in the subsurface, an azimuth moveout exists in the reflection events of CMP trace gather. From DMO and inverse DMO in f k domain, this paper derives the time and amplitude formulas of AMO impulse responses by stationary phase, according to the basic principle of azimuth moveout(AMO).AMO has been applied to a swath of 3 D practical seismic data processing and satisfactory results have been gotten, which have enhanced the diffractions and the reflections from fault plane. |
