应用正演模拟分析近地表黏弹性对深层缝洞储层地震波衰减及成像的影响
Keywords: 近地表,正演模拟,黏弹介质,吸收衰减
Abstract:
？近地表沙层的黏弹特性引起的地震波能量及频率的吸收衰减不容忽视。本文基于黏弹性介质波动方程正演模拟技术，研究了近地表不同q值情况下地震波穿过黏弹介质后的地震波场特征，通过波场频谱特征分析了影响地震波能量及频率吸收衰减的因素，即q值越小、激发子波的主频越高、传播距离越远的地震波能量及主频吸收衰减越严重。在此基础上建立起伏地表沙层缝洞型模型，研究近地表沙层对中深部储层反射波的衰减及对缝洞型储层成像的影响，对实际地震资料的振幅、频率的恢复补偿以及提高分辨率具有一定意义。
