拟声波曲线重构在储层预测中的应用

Application of Pseudo-acoustic Curve Rebuild in Reservoir Predication

针对常规声波测井的不足提出拟声波曲线重构技术,以提高使用测井资料进行地震层位标定的准确性和地震资料反演的分辨率。实验结果表明,拟声波曲线能很好地反映出探井地层岩性的纵向变化,且拟声波曲线反演效果明显优于原声波曲线的反演结果。

In view of the shortcomings of the current conventional reservoir prediction method, someone proposed reconstruction of pseudo-acoustic curve. Pseudo-acoustic curve to be reconstructed using existing logging data, to make up for the lack of sonic logging, logging data used to improve seismic horizon and the accuracy of the calibration of seismic data inversion. The results showed that pseudo-acoustic curve to be well reflected in the exploratory well lithology changes in the vertical and pseudo-acoustic curve inversion results to be better than the sound wave curve inversion results.
