希尔伯特变换在测井资料数据处理中的应用
|
摘要
希尔伯特变换是建立在复地震道技术基础上的一种处理方法．从广义上讲，地震资料与测井资料有许多相似的地方，因此该方法可以平行地应用到测井资料的处理中去．选取了不同类型的测井曲线进行了尝试，结果发现：该方法对横向电阻率测井的效果比较理想，处理后其分辨率有明显提高．通过分析对比发现瞬时振幅曲线和瞬时频率曲线对岩性的变化比较明显，特别是瞬时频率曲线对岩性的变化非常敏感，这一现象是地层的砂泥岩薄互层的交替出现所致．
Hilbert transform is a processing method which is based on complex seismic trace technology. In the broad sense, well logging data is similar to that of seismic data in many ways. Therefore,we can apply Hilbert transform in well logging data processing just like in seismic data processing. In practical processing, we selected different types of well logging data, and we found RLLD well logging data has more desirable results,the resolution of processed results improved obviously. Through comparison and analysis,we found transient amplitude and transient frequency information are more sensitive to the lithology than others,especially transivent frequency information.
