【摘要】：为了充分利用地震记录中的绕射波信息刻画地下小尺度构造(断层、尖灭、裂缝、盐丘侧翼等),本文在高斯束偏移过程中,借助倾角扫描及运动学与动力学射线追踪方法,构建反稳相滤波算子,发展了一种基于反稳相策略的深度域绕射波分离成像方法。在编程实现算法的基础上,通过国际标准的Sigsbee 2A模型验证了本文方法的正确性。同时,利用实际资料绕射波分离成像测试,验证了方法对陆上实际资料具有较好的适用性。
[Abstract]:In order to make full use of the diffraction wave information in seismic records to depict small scale underground structures (faults, pinches, fractures, flanks of salt dome, etc.), in the process of Gao Si beam migration, dip scanning and kinematic and dynamic ray tracing methods are used in this paper. An inverse phase filter operator is constructed and a depth domain diffractive wave separation imaging method based on the inverse phase stabilization strategy is developed. On the basis of programming algorithm, the correctness of this method is verified by the international standard Sigsbee 2A model. At the same time, the application of the method to the real land data is verified by using the diffraction wave separation imaging test of the actual data.
