叠前反演中部分叠加道集的优化校正
Keywords: 叠前反演,部分道集,数据校正,均方根振幅指数,预测指数
Abstract:
？在叠前反演过程中,常常遇到近、中、远部分道集叠加的时间、振幅等不闭合现象,其结果导致弹性参数反演的质量与可信度下降。本文使用目标层位控制、残差数据相关性判别、质控因子等方法进行部分道集数据的闭合校正。首先确定期望输出道集数据以及相应的目标层位与时窗后,计算待校正数据与期望输出数据的残差互相关系数;再利用相关系数判别待校正道集与期望输出道集的相关程度,对不符合反演要求的道集数据,引入均方根振幅指数、预测指数这两个质控因子对待校正道集进行优化;最后使其与期望输出道集较好闭合。实例证明,利用归一化均方根振幅指数和预测指数因子优化时移量和振幅缩放系数,能够相对可靠的控制部分道集校正的质量,提高叠前反演的效果。
