随着地震勘探技术的不断发展,地震剖面的成像技术也日益完善。从早先的人工几何作图绘制剖面到现在的时间剖面,这是一个进步。但在构造复杂的地区,时间剖面不能真实地反映地下剖面情况。因此,出现了各种偏移方法,其中有根据绕射理论发展起来的绕射扫描迭加、克雷尔伯特波动方程差分解法和根据克希霍夫积分的解法。这些方法使地震剖面成像技术推进到更高的阶段。绕射扫描迭加仅仅是克希霍夫积分解法的几何近似,克雷尔伯特差分解法仅适合于界面倾角不大的情况。当倾角大时波散现象严重。近来有些文献发展了他的方法,使它的应用范围扩大了。克希霍夫积分解法可适用于陡 With the continuous development of seismic exploration technology, seismic profile imaging technology is also increasingly improved. It is a step forward from the previous artificial geometry plot to the current time profile. However, in the complicated area, the time profile can not truly reflect the underground profile. Therefore, various offset methods have appeared, among which there are diffraction scanning superpositions developed according to the diffraction theory, the differential solution of Kerell’s wave equation and the solution according to Kirchhoff’s integral. These methods have advanced seismic profiling imaging to a higher level. The superposition of diffraction scan is only the geometric approximation of Kirchhoff’s integral solution. The Kleber’s differential method is only suitable for the case of small interface inclination. When the inclination is large, the phenomenon of divergence is serious. Some recent literature has developed his method, making its application expanded. Kirchhoff’s integral solution is suitable for steepness
