| 摘 要： | 重点阐述了基于地震属性的地震相分析方法。了解区域地质概况、沉积背景,选取完整的沉积体系;选取合适的时窗沿层提取地震属性（RMS,平均瞬时频率、有效带宽）,利用RMS属性识别沉积体,平均瞬时频率判断物源方向,有效带宽推测沉积环境及地层的均质性;综合考虑最终确定沉积体的地震相特征,绘制该层段的地震相平面图;最后将地震相转相为沉积相。利用该方法对尼日尔三角洲S工区进行地震相分析,识别出高弯度水道、水道-朵叶复合体、末端朵叶等沉积体的典型地震相特征,取得很好的效果,显示该方法具有良好的应用前景。 |
| 关 键 词： | 地震相 均方根属性 平均瞬时频率 有效带宽 高弯度水道 |

| Abstract: | In this paper,the seismic facies analysis method based on seismic attributes is mainly described.Firstly,the regional geological survey and sedimentary background are given.Then the method is introduced as this: the complete sedimentary system is selected and the seismic attributes(RMS,Average Instantaneous Frequency,Effective Bandwidth,etc)are extracted from the appropriate time-window along an event;the attribute of RMS amplitude is used to identify the sedimentary bodies;average instantaneous frequency i... |
| Keywords: | seismic facies RMS amplitude the average instantaneous frequency effective bandwidth high-sinuosity channel |
