曲线重构技术在富安次凹阜三段储层预测中的运用

Application of curve reconstruction for reservoir prediction in Fu3 section of Fuan Sag

富安次凹阜三段主要为泥岩夹薄层砂的沉积,常规反演不能满足要求。需要采取新的反演方法以提高储层预测精度。鉴于此,提出利用自然电位对实测声波曲线进行重构的方法,应用重构后的拟声波曲线进行储层预测,以提高砂、泥岩波阻抗的差异性,有效地提高反演剖面的分辨率。

Fuan Sag deposites mudstone with thin sandstone in Fu3 section,and the conventional inversion can not meet the requirement. It needs to take a new inversion method to improve the precision of reservoir prediction. A method is put forward to reconstruct the measured acoustic log by using SP. The reconstructed pseudo acoustic curve was used to predict the reservoir,to improve the difference of wave impedance,and the inversion resolution was effectively raised.
