波形分析影响因素分析

The Analysis of Factors Influencing The Waveform Analysis

利用波形分析对涠西南凹陷流三段进行地震相划分及储层研究,取得了较好的预测效果。波形分析受多种因素影响,主要有波形与井储层物性相关性分析;波形与储层发育程度关系,通过研究不同沉积模式、不同区域下的储层,发现波形信息有所差别,这些差别是影响波形分析效果的重要方面;波形分类还要参照地质认识,反复调试波形参数,使波形分类与地质认识相结合,最终划分出合理的地震相。

Using waveform analysis it has good effect which draw the distribution of seismic facies and predict reservoir in L3 formation of Weixinan depression.It has many factors which effect waveform analysis.First,the relativety between waveform and physical property of the wells;second,the relationship between waveform and reservoir development,we find waveforms different when the reservoirs are in different deposit mode and area.IT's a important way of influencing the effects of waveform analysis;in the end,we should consult geological cognitions,debug parameters through and through,combine waveform analysis and geological cognitions,plot out the seismic facies.
