| 摘 要： | 地质体在应力场的作用下发生弹性形变,从而具有应变位能（势能）。应用应变位能公式,可以将位或位移转化为势能,用势能剖面代替常规地震剖面。由于势能转换能拓宽地震信号的有效频谱,具有高通滤波性质,同时又不损害低频信号,所以,同常规地震剖面相比,势能剖面在保持信噪比的前提下,有更高的纵、横向分辨率。通过势能转换的理论分析及合成数据和实际数据的势能转换处理,本文系统地研究了势能转化问题和实现方法,从而证明势能转换确实是行之有效的高分辨率地震处理方法,可用于实际地震资料的处理。

| Abstract: | Seismic signal reflected from layers of different velocity under earth represents the geological particles displacement or potential （assuming the geological body was made up of numerously separable particles）.In fact,every particle vibration has also potential power.When we de'scribe the particle's properties with potential power instead of displacement,we may reasonably expect to gain high-resolution seismic data since the differential operator is actually a high-pass filter.We have systematically studied the replacement of displacement with potential power both in theory and practice.It is concluded that the replacement is surly a feasible processing method of high-resolution. |
