| 摘 要： | 地层对比的精度和准确性关系到是否能发现以前漏掉的储集层.提出了小波时频分析地层对比方法,用一维连续小波变换埘测井资料进行处理,得出不同尺度的小波时频特征.即用频率的周期旋回变化来标定各级地层的级别并控制各级地层的对比,包括小层、砂层组及单砂层对比追踪.在长庆油区延长组的应用证明了该方法的有效性.

| Abstract: | Stratum correlation is the basic geological research in developing oilfields,the correlation precision and correction have close relation with whether some new pay zones could be found or not.Therefore,proposed is a wavelet time-frequency analysis method for stratum correlation interpretation.With one-dimensional CWT in the log data processing,we get wavelet time-frequency characteristics of different scales,that is,to scale stratum of all levels and control the correlation of stratum of all levels by the c... |
