摘要(Abstract)：

在高分辨率地震资料处理过程中,为提取非卷绕的混合相位子波,使提高分辨率后的反射系数具有"蓝谱"特征,利用多路径平均求取高阶相位谱中非卷绕的相位主值,提取地震子波真实相位,通过重构地震子波进行确定性反褶积;利用测井资料和谱拟合得到与研究区沉积特点相符合的地层反射系数谱的分布特征,进行谱的交互式"蓝色"补偿,提高地震资料的分辨率和保真性.资料处理结果表明:该方法能估算非卷绕的混合相位子波,进行交互式"蓝谱"补偿,处理后剖面分辨率较高、保真性较好,能够有效提高地震记录分辨率.

关键词(KeyWords)：地震记录;非卷绕相位;反褶积;交互式处理;测井资料;高阶谱;分辨率
