In this paper, a new application of the spectral element method (SEM) is proposed, which is combined by the features of the fracture-only reservoir simulation technique. This method has been examined with the numerical simulation of waterflooding recovery mechanism. The effect of co-current imbibition is exhibited by a fracture flow analysis with an impermeable porous media. This analysis has been then repeated to study counter-current imbibition effect considering a homogeneous porous media. The capability of the fracture-only technique has been demonstrated more by analyzing fracture flow with heterogeneous porous media. All the presented SEM's results have shown a closeness agreement with the valid results obtained by analytical and streamline-based formulations. The SEM presented 36% higher accuracy when compared to the solution obtained by the finite element method (FEM).

本文结合纯裂缝储层模拟技术的特点，提出了光谱元法（SEM）的新应用。该方法已通过注水采收机制的数值模拟得到检验。并流渗吸的影响通过不渗透多孔介质的裂缝流动分析显示出来。然后重复该分析以研究考虑均质多孔介质的逆流渗吸效应。通过分析非均质多孔介质的裂缝流动，更多地证明了仅裂缝技术的能力。所有呈现的 SEM 结果都与通过分析和基于流线的公式获得的有效结果非常吻合。
