摘要
层厚的确定是地震资料解释的重要组成部分。对15°经验法和陡倾角地层层厚的计算进行了讨论,分析了层拉平校正方法的误差,并讨论了应用校正的地质条件。应用该方法对某盆地Y构造带H22段油层等厚图进行处理,效果十分显著。
Determination of thick layers is an important part of seismic inter pretation.This paper discusses thickness cal-culation of layers with steep dip by using the15°empirical method,analyzes the error of bedding flattening co rrection method,and discusses the geologic conditions for utilization of the fl attening method.Correction to the isopach map of T 12 4 layer in a basin with this method had achieved remark-able effects.
