| 摘 要： | 本文介绍了一种利用偶极声波和密度测井资料进行叠前道集正演，对实际地震处理道集振幅随偏移距距变化特征进行对比和监控的方法。通过采用实测偶极声波和密度测井资料，利用Zoeppritz方程及其近似公式计算井的叠前正演道集，选取沉积稳定的区域标志层，分析其截距和梯度属性。通过对比正演AVO道集和井旁实际偏移道集波组特征及AVO属性特征，达到检验处理过程和结果是否保幅的目的，实现了AVO特征定量监控。

| Abstract: | This paper introduces a method comparing and controlling the changes of track amplitudes varying with displacements during processing seismic data, which applies dipole sonic logging and density logging to pre-stack forward track modeling. By using Zoeppritz function and its similar equations, the pre stack forward track is measured in intercept and gradient attributes based on a stable sedimentary mark layer. Through comparison between forward AVO track, practical displacement track wave features by wells and AVO attributes, the amplitude is retained from processing and results, which achieves a quantitative control of AVO features. |
