两种薄层弹性参数多波联合反演的对比

针对薄层及多波联合反演两大研究热点,以薄层频率域反、透射系数为基础,建立了两类薄煤层模型——强阻抗和低阻抗差异薄层,并对其分别进行单纯P波、S波及PP波与PS波联合反演。利用反演结果及误差分析,对比了单种波反演和联合反演的效果,从模型反演数据证实了对于薄层而言,PP波和PS波联合反演比P波或者S波单纯反演具有更好的效果。

地震散射波模拟成像方法在铜陵某矿区的应用

针对深部隐伏的金属矿床,以铜陵某矿区为例,应用散射波正演模拟技术,对金属矿地震数据野外采集中涉及的偏移距、覆盖次数、道间距等参数进行了不同炮记录的模拟对比,辅助指导非均匀地质体金属矿地震勘探野外数据采集的观测系统设计;针对该地区实际采集的地震数据,应用基于等效偏移距的共散射点成像方法,对金属矿地震数据进行了处理,通过与常规反射波法处理结果对比,散射成像效果较好,说明散射波技术在金属矿地震勘探中应用有一定的可行性和适用性.
