本文简要地阐述了高分辨率地震资料处理的一般原理和方法;介绍了弥陀场工区两条正交高分辨率测线的处理情况,比较详细地分析了资料的处理效果。地震资料的分辨率主要取决于子波的频带宽度、振幅谱形态以及子波的相位特性。箱形谱、零相位、宽频子波的分辨率最高。高分辨地震资料处理的基本目标是把野外记录到的具有一定时变空变特点的子波尽可能转换成时不变的、空不变的、振幅谱为箱形的零相位子波。在弥陀场工区高分辨率地震资料的处理中,我们通过道编辑、叠加方式的选取以及高保真去噪声方法提高信噪比,拓宽有效频带宽度(我们把信噪比大于等于1的所有频率成分的集合定义为地震资料的有效频带);通过SCALCOMP消除了大部分与岩性无关的横向振幅变化;通过DESIG、QCOMP及TCOMP把振幅谱整形为时变作用较小的白色谱;通过NMP处理获得零相位子波。经过上述处理,资料的有效波频带宽度达到10~110Hz,相对频带宽度约为3个倍频程,子波近似为10~100Hz的零相位Sine子波;在高速的碳酸盐岩地区,薄层分辨力约为15~23m,与常规地震剖面相比分辨率有了明显提高。
