Fuzzy structural element method for solving fuzzy dual medium seepage model in reservoir

This study primarily introduces fuzzy set theory in the reservoirs modeling to enhance the accuracy of the model. The conventional seepage models of dual medium in reservoirs have several limitations. To be specific, it considers the complexity of the model during the modeling process and idealizes certain reservoir parameters to be constant. By adopting fuzzy set theory to study reservoir seepage theory, on the one hand, the seepage model is capable of fully considering the complex and variability of the reservoir; on the other hand, it can avoid parameter errors attributed to laboratory measurements. A numerical example is given in this study to illustrate the accuracy and superiority of the fuzzy seepage model. Studies suggest that fuzzy set theory is capable of effectively addressing the limitations in conventional seepage models.
