摘要

油田进入高含水期,储层参数发生了变化。用传统的解释方法计算渗透率很难达到理想的精度。作者提出利用储层流体流动单元流动带指标反算渗透率的方法,并应用于辽河油田欢26断块高含水油田储层评价中,取得了良好的应用效果。

Abstract：

After entering the highly water-bearing period, the reservoir fundamental parameters would remarkably change. The precision of calculating permeability can hardly be achieved by traditional methods. In this paper, a new method is put forward, which calculates permeability on the basis of reservoir fluid flow unit. This method was applied to the reservoir evaluation of Block Huan26 in the Liaohe oilfield, with satisfactory results obtained.

Key words： gravity anomaly signal frequency spectrum FIR filter discrete Fourier transform (DFT) frequency sampling method
