摘要

研究切片的应用条件和分辨率对更好的利用切片具有重要意义，针对这2方面采用正演模拟进行了探讨。研究表明，地层切片仅适用于小于地震分辨率的薄层储层|地层切片的范围应大于或局部大于沉积体系的规模，且参考层间的地层厚度不能剧烈变化。切片的分辨率可以用检测率来表示，检测率满足横向分辨率往往小于垂向分辨率，薄层情况下，切片的分辨率比时窗属性的分辨率更高，地震资料的品质、地质背景以及所采用的切片方法是切片分辨率的重要影响因素。分频技术并不能改善地震资料品质和提高分辨率，但可以突出储层的有效信息|与薄互层情况下的地震切片相比，单一薄层情况下(泥包砂)的地震切片分辨率更高|保证切片的相对地质等时是地质体能够识别的基础。

Abstract

The application condition and resolution of slice were discussed in this study according to the forward modeling which is important to use it better.The research shows that，stratal slice is only suitable for the thin reservoirs which are less than the seismic resolution.The range of stratal slices should be greater or locally larger than the scale of sedimentary system, and the thickness of strata between the reference layers cannot change dramatically.The slice resolution should be represented with a detection rate, which meets the lateral resolution and is often less than the vertical resolution.The slice resolution is higher than time-window properties in thin layer.The quality of seismic data，the geological background and slice method are important factors affecting slice resolution.Frequency division cannot improve quality and the resolution of seismic data，but can enhance the effective information of reservoir.The slice resolution of single thin layer is greater than thin interbedded layer.To keep slice relative geological isochronous is the basis for the geological body to be identified.
