摘要
ＳＬＬＪ地区Ｅｓｓ４ 的冲积扇具有五层微沉积序列，本文利用从三维地震资料中提取的多种地震参数，首先对参数用Ｋ－Ｌ法压缩处理，然后与各层砂砾层厚度用最小二乘法拟合改造后，再进行主特征因子分析求取各微层序的钻井加权地震相因子值，并转化为地震相平面图，通过与钻井相、测井相三相综合分析，成功地将其转化为各微层序的沉积微相平面图。因此本文提供了一种从地震角度进行微沉积层序研究的方法。
There are five sedimentary microsequencies of E s s 4's fluvial fan in SLLJ region. The authors get many special wave parameters from 3D seismic data and compress them in order to lessen their numbers by K L method. After making correlation analysis with sand thickness, the authors can get every microsequence's drilling weighting seismic facies factors using main characteristic factor analysis and make them into seismic microfacies distributions. On the basic of integrated analysis with drilling microfacies and logging microfacies, the authors successfully convert them into sedimentary microfacies distribution. So this paper offers a method for sedimentary microfacies analysis from seismic data, and it is very useful to the sedimentary research of complicated lithology.
