反射波振幅受多种因素影响,其中包括记录系统影响、波阵面几何扩散影响、非理想弹性介质影响及反射界面曲率影响等.在当前的地震数字处理技术中,对前三者已能有成效地进行定量校正,对反射界面曲率影响则尚缺乏完整的定量讨论分析.具有正曲率的凸界面使反射能量发散,具有负曲率的凹界面在一定条件下可使反射能量聚焦,这些都是众所周知的事实.诸如时间剖面上的背斜顶部的所谓“秃顶”现象,以及“亮点”技术中出现的虚假振幅异常——隆起顶部存在“暗点”、凹陷底部却出现“亮点”等 The amplitude of the reflected wave is affected by many factors, including the influence of the recording system, the geometric diffusion of the wavefront, the influence of the non-ideal elastic medium and the curvature of the reflective interface, etc. In the current seismic digital processing technologies, The quantitative correction is effective and there is no complete quantitative discussion on the influence of the reflection interface curvature.The convex interface with the positive curvature diverges the reflection energy and the concave interface with the negative curvature can focus the reflection energy under certain conditions It is a well-known fact that the so-called “baldness” phenomenon such as the top of the anticlines on the time profile and the false amplitude anomalies that occur in the “bright spot” technique have “dark spots” at the top of the bump and “bright spots” at the bottom of the pit
