摘要

20世纪90年代以来, 地震油气储层预测新技术取得了巨大发展, S trat imag ic地

震波形分类技术就是其中之一。该技术是研究各沉积相单元发生变化时的地震反射特征, 然

后利用神经网络技术把地震信号的总体趋势变化定量地反映出来(对波形进行分类), 形成地

震波形异常, 即地震相图。在综合地质分析基础上, 针对目前红浅一井区勘探实际情况, 应用

这一技术对该地区主要目的层段辫状河道砂体进行了准确预测, 并取得了良好效果。

Abstract

Seismic reservo ir pred iction techno logy has been greatly
developed since 90s. One o f them is Stra tim ag ic se ism ic
w aveform class ification techno logy. Th is paper studies the
characteristics of se ism ic re flection as sedim en tary fac ies
change, and then quantifies general vary ing trends of se ism ic
signal by neura-l netw ork techno logy, nam e ly se ism ic
w aveform classification and abno rm al se ism ic w aveform o r
se ism ic facies m ap. Through comprehens ive geolog ica l
analysis, the a rtic le desc ribes the application of abov em
entioned techno logy and accurate ly pred ic ts bra ided channe l
sand o f targe t stratigraphy in H ongqian a rea based on facts of
exploration in H ongqian d illing area. A good result has been
ach ieved.
