小波分析技术近几年在地震资料的处理方面得到了较为广泛的应用 ,但在地震资料的解释和油藏描述方面还很少见有应用。通过小波变换基本理论的分析 ,说明了小波变换能够提高地震资料分辨率 ,从而达到识别薄砂岩储集层的目的 ;尝试了小波分析技术应用于薄砂层识别及描述 ,并结合埕岛地区馆陶组上段曲流河薄砂岩储层的描述 ,介绍了其实现过程及取得的效果 ,指出小波分析技术在薄砂岩储层发育的油气区是一项非常有效的描述技术和方法 Wavelet analysis technology has been widely used in seismic data processing in recent years, but it is seldom applied in seismic data interpretation and reservoir description. Based on the analysis of the basic theory of wavelet transform, it is demonstrated that wavelet transform can improve the resolution of seismic data and achieve the purpose of identifying thin sandstone reservoirs. Wavelet analysis technology is applied to the identification and description of thin sand layers. The description of the meandering thin sandstone reservoirs in the Upper Triassic of the Taohe Formation is introduced, and the realization process and the obtained results are introduced. It is pointed out that the wavelet analysis technique is a very effective description technique and method for the development of thin sandstone reservoirs.
